Great!

The rules for a branch are, generally, up to the branch owner.  The
only one I'll insist on is that copyright assignments be handled in the
same way as for HEAD, which is not a problem here.  See:

  http://sources.redhat.com/gdb/current/onlinedocs/gdbint_15.html#SEC133

(which are mostly guidelines rather than rules).  So, you can create a
branch if you'd like.

I took a quick look at the changes, but couldn't make heads or tails
out of what was going on.  Also, I think the diff is corrupted; the
changes to linux-nat.c cut off in a very strange place in child_wait().
Maybe when it's been cleaned up a little we can look for a way to do
this that doesn't involve pthreads.
