I think there are many underlying bugs in openssl library when implemented
on a non blocking way. Openssl only works as spected if you fork on connect
and use blocking IO otherwise I always got weird results. May be GNU TLS is
a better option ? But I don't know how mature it is.

I'll give It a try tomorrow morning on my next maintenance window.
