free mutex attr before mutex. as per:

http://docs.sun.com/app/docs/doc/802-1949/6i5ur8qam?a=view

"If a mutex is dynamically allocated and was initialized with an
attribute object, its attribute object should be freed with
pthread_mutexattr_destroy() before the mutex itself is freed."

Rows in the I_S plugin object make it not thread safe. Due to the way we do subselects, it's also recursive (fillTable can call fillTable).... so we have a recursive mutex.
