[RFA]: Test for threads attach/detach

[RFA]: Test for threads attach/detach

[Mark Kettenis]

Better get aproval for this stuff first :-).

This is supposed to test attaching to a multi-threaded program.  Only
executed on Linux for now.

OK, to check this in?

   Hey Mark, 
   Did you ever get resolution for this new test?
   Michael

Nope.  What do you think about it.  In the MAINTAINERS file we have:

testsuite
  ...
  threads (gdb.threads) Michael Snyder          msnyder@redhat.com

so you'll just have to mumble something that sounds like OK, and I'll
check it in :-).
