> After generating a load against JBossAS 4.2 beta1, the cpu is pegged at 100% even after the load has stopped.  A thread dump reveals several threads at TransactionReaper.insert().  These threads are all doing a WeakHashMap.get().  Looking at TransactionReaper, I believe this is caused by unsynchronized access to the _timeouts WeakHahsMap.  This is line 324 in TransactionReaper.java.
