Subject: Bug #27964: pthread_key_create doesn't set errno, so don't report \ 
 errno

Vasil Dimov (at Oracle) noted that pthread_key_create() does not
set errno, so if it fails then we return the wrong error code.

Instead, capture the return value, which is the real error value,
and instead report that.
