[event] PooledExecutor locking up?

[Peter Royal]

It appears that my PooledExecutor is locking up... From a thread dump:

"Thread-6" prio=1 tid=0x0x8637fc8 nid=0x1292 in Object.wait()  
[89bcd000..89bcd830]
        at java.lang.Object.wait(Native Method)
        - waiting on <0x4dde3d28> (a

r.java:725)
        at java.lang.Thread.run(Thread.java:536)

I'm really unsure of how to go about properly fixing that.. as a  
workaround I'm going to modify TPCThreadManager to not block  
(PoolExecutor.discardOldestWhenBlocked())
