FYI: Increase in schedlock.exp failures in LinuxThreads on an RH kernel

We won't ask.  But, as you might imagine, we do run the gdb test suite on
our kernels, and we haven't seen this.  So you indeed must have hit upon a
lucky combination of hardware and software between that RH kernel and your
Debian userland that happens to bite.

We probably will.  I always used that patch when debugging the kernel
signals code in the past.
