Add patch from firstname.lastname@example.org to initialize thread keys to -1
Errors were being seen in libpthread/libdl that were related
to corrupt thread specific keys. Global destructors that are called on dl
unload. During destruction delete a thread specific key without checking
if it has been initialized. Since the constructor is not called each time
(i.e. key is not initialized with pthread_key_create each time), and the
default is 0, there is a possibility that key 0 for an active thread gets
deleted. This is exactly what is happening in case of OpenJDK.
