ssh-keygen freezes if you force use of engine

Yeah the problem is **definitely** that the function 
"OPENSSL_init_crypto" is calling itself recursively.

I might have to put in a thread-duration variable to keep track of the 
stack depth, and only tell it to load the config file on the first call.

I also tried playing around with OPENSSL_SSL_CLIENT_ENGINE_AUTO at compile 
time, but I can't seem to get it to work.


Here's my latest stack trace when I link statically with libcrypto.a:

OPENSSL_init_crypto, with the following backtrace:
