Actually I fixed some things in the patch, see below ...
It makes more sense to test whether the socket is in blocking mode, even
if a client ssl socket doesn't need multiple calls to
stream_socket_enable_crypto()

Here is a patch to fix this issue (diff against 5.3.0)
As far as I have tested, everything works as expected with this patch
applied.

FYI:
I can't repro this on Windows with the build off the snaps' box (VC9 x86
Non Thread Safe (2009-Aug-18 16:00:00)).
It:
blocks until connection using telnet[expected]
doens't consume any CPU[expected]
and returns 'bool(false)' [expected -- I assume the same as 'int(0)']
and exits[expected]
