+In my research into this bug, I've managed to find that the freeze
+occurs when libgc is performing a garbage collection. If you run the
+test class listed above with the environment variable GC_PRINT_STATS
+set, you will see that the very last output to the console is
+"Initiating full world-stop collection <x> after <y> allocd bytes"
+I've also verified that the issue with xsp freezing is related, the
+same message is printed when it freezes on an nptl enabled glibc.
+At this point in time, all threads are in a wait state.
+An interesting thing I found out is that if you set a breakpoint in
+the libgc code that prints the message, it will be continuously hit
+once the app has frozen. And in some cases I even saw the garbage
+collector repeatedly trying to collect the same identical heap.
