[jboss-as7-dev] Build hangs in controller module

[Brian Stansberry]

I'll look at this over the weekend. The 2nd thread dump makes me suspect 
a concurrency or other bug in the management code; the "main" thread 
invoked a managment op and is blocking waiting for a notification of 
completion. No other thread is doing anything, so either the 
notification got missed (concurrency) or some other bug caused it to not 
get emitted.

It doesn't happen all the time, which smells more like a concurrency issue.
