You don't say what OS or version of boost you are using, but it sounds like
an old problem. Try looking at

the mailing list archives.

Subject: [Discuss-gnuradio] hanging on top_block.stop
Hi all,
The following script hangs for me about 1 time in 10 on the call to
top_block.stop.
Drilling in a bit, it appears to get stuck on a call to 'interrupt' of
a boost::thread instance on line 91 of gruel/src/lib/thread_group.cc.
Has anyone else had this problem?
Cheers,
Ben
