Without SSL_MODE_AUTO_RETRY, even blocking mode will return
SSL_ERROR_WANT_{READ|WRITE} in the event of a renegotiation.
The comments in the code speak only of "nasty problems" unless this is
done. The original commit that added SSL_MODE_AUTO_RETRY
(54f10e6adce56eb2e59936e32216162aadc5d050) gives a little more detail:
The [...] behaviour is needed by applications such as s_client and
s_server that use select() to determine when to use SSL_read.
Without the -nbio flag, s_client will use select() to find when the
socket is readable and then call SSL_read with a blocking socket.
However, this will still block in the event of an incomplete record, so
the delay is already unbounded. This it's very unclear what the point of
this behaviour ever was.
Perhaps if the read and write paths were different sockets where the
read socket was non-blocking but the write socket was blocking. But that
seems like an implausible situation to worry too much about.

Some archaeology: it was added in upstream's
ee1d9ec019a7584482bd95891404f1cad66a4a0a. This seems to come from upstream's
arrangement where an EVP_MD can specify both the signing algorithm and the
message digest. (Most of the usual hash algorithms were tied to RSA.)
The flag is set on EVP_MDs that should use the EVP_PKEY's method table in
EVP_Sign* rather than the one attached to the EVP_MD (there's also
required_pkey_type to filter on EVP_PKEY to prevent a mismatch). Without the
flag, the old codepath is hit where they're tied together.
Interestingly, EVP_md5 does not have the flag, but I suppose this is because no
one would sign ECDSA + MD5. EVP_DigestSign* also postdates this and doesn't use
the legacy mechanism anyway. Upstream also has, e.g., EVP_ecdsa(). Although
those too have since also gained the flag in
bce1af776247fee153223ea156228810779483ce.
Let's get rid of these TODOs. We don't have the old codepath. It's unclear if
upstream really does either at this point.
Note: EVP_PKEY_RSA_method in upstream is actually a macro that expands to three
fields, which is why it's so difficult to figure out what's going on with those
structs.

Doing some archeaology, since the initial OpenSSL commit, key_arg has been
omitted from the serialization if key_arg_length was 0. Since this is an
SSLv2-only field and resuming an SSLv2 session with SSLv3+ is not possible,
there is no need to support parsing those sessions.
Interestingly, it is actually not the case that key_arg_length was only ever
set in SSLv2, historically. In the initial commit of OpenSSL, SSLeay 0.8.1b,
key_arg was used to store what appears to be the IV. That was then removed in
the next commit, an import of SSLeay 0.9.0b, at which point key_arg was only
ever set in SSLv3. That is old enough that there is certainly no need to
parse pre-SSLeay-0.9.0b sessions...
