credis_connect() calls gethostbyname(), which is not reentrant about credis HOT 6 CLOSED

I can take a stab at a patch later in the week if it helps.

Cheers.

Ooops I missed that lots of people ask me if credis is thread safe and I've 
told them yes, it should be... I reused an old snippet when starting on Credis 
so I will gladly accept a patch that fixes this issue.

cheers,

Question--

gethostbyname() is only called in the event that inet_aton(host, &sa.sin_addr) 
fails.  On my system, it doesn't fail, so I haven't had any issues with thread 
safety.  My question is:  When would inet_aton fail that gethostbyname() would 
succeed?

This should do it for the non-Win build.  I did not check the Win side, but I 
don't think I broke anything.  Shout if I messed up--still learning the ropes...

thanks, I have taken your patch with minor changes
