Is the OpenSSL library supposed to be at all reentrant? I've had odd

program (multiple threads each dealing with independent SSL connections),
and have apparently solved them by creating a single global mutex and
wrapping a mutex acquire around every call into the library. Is
this kind of locking expected to be needed?
This should not be needed so long as you follow two rules:
1) You must properly set the multi-threaded locking callback.
2) You must not attempt to access the same object directly from two
threads at the same time. For example, you cannot call SSL_read and
SSL_write concurrently on the same SSL object.
