malloc: checked_request2size failure deadlocks
For some rarely cases(almost App bugs), calling malloc with a very largre size, checked_request2size check will fail,set ENOMEM, and return 0 to caller. But this will let __malloc_lock futex locked and owned by the caller. In multithread circumstance, other thread calling malloc/calloc will NOT succeed and get locked.
