Description
closed/runtime/6471091/Test6471091.java
hangs once in a few times (this is a race test)
see comments on how to reproduce this.
Initially reproduced with /net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/16/pit/b07/jdk7b67/product/solaris-i586
also reproduced with
/net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/16/pit/b04/jdk7b61/product/solaris-i586
and releases in between, looks like this takes more iterations though (80).
