This is what's causing the segfault in libpthread.so

I can only imagine that the same thread is trying to re-lock a single-lock 
mutex. So my code should be something like:


int already_locked_meth = is_already_locked(rand_meth_lock);
int already_locked_engine = is_already_locked(rand_engine_lock);

if (!already_locked_meth)
        CRYPTO_THREAD_write_lock(rand_meth_lock);       

if (!already_locked_engine)
        CRYPTO_THREAD_write_lock(rand_engine_lock);


/* DO STUFF */

if (!already_locked_meth)
        CRYPTO_THREAD_unlock(rand_meth_lock);           

if (!already_locked_engine)
        CRYPTO_THREAD_unlock(rand_engine_lock);
