   Hmm.  That might be gdb trying to talk to the signal thread.

Definitely.

   But there is no excuse for C-c not working in gdb.
   Someone should debug gdb.

Hmm. C-c is supposed to interrupt the program, which obviously fails
because the signal thread isn't responding.  Should it interrupt GDB
instead in such a case?

   There might be some hurdish gdb options you should set before attaching.
   "set signals" or something. 

"set noninvasive on" should do the trick.
