It's sufficient to just call SSL_load_error_strings for error string 
initialization; that function itself calls ERR_load_crypto_strings (and 
ERR_load_ssl_strings) so calling both is redundant.

SSL_library_init(3) recommends the init sequence of just 
SSL_load_error_strings then SSL_library_init.  It's definitely necessary 
to call the latter at some point - from looking at OpenSSL 0.9.8a at 
least there is work done in there which is not done anywhere else.

CRYPTO_malloc_init looks like it will only make a difference on Win32 
but I suppose should be called first if used at all.

So, I guess the recommended init sequence would be:


But like you say this doesn't cover the thread-safety stuff; also some 
of the ENGINE stuff is process-global IIRC.  All hail global state :(
