Issue when getting portlet windows from cache

[Ethan Adams <et...@gmail.com>]

I am running a load test on J2 FINAL (Solaris 8, Java 1.5, Oracle 9) and
noticed that the java utilization spiked to 100% (it was running around
45%).  I did a thread dump using kill -3 and found 200 of these:

"TP-Processor1" daemon prio=10 tid=0x01009fc8 nid=0x47 runnable
