How can you guarantee those real-time signals are not used for
other purposes? We have __libc_allocate_rtsig () in <signal.h>.
I can image someone wants to call it to get a free signal.

BTW, I will make gdb 4.17.0.11 next week. I will make my 2 patches for
glibc 2.1 available if you don't want them in glibc 2.1 unless you can
provide me a patch for gdb which is as reliable as gdb 4.17.0.11.

Thanks.
