Setting AIX threading parameters

The IBM JVM threading and synchronization components are based upon the AIX Posix compliant Pthread implementation. The following environments variables have been found to improve Java performance in many situations and have been used for the benchmarks in this document. The variables control the mapping of Java threads to AIX Native threads, turn off mapping information, and allow for spinning on Mutex locks.
