Attempting to attach to a running process seems to hang both GDB and the
running process:

Quitting: ptrace: No such process.
I have recreated with a hello-world type program (attached).
compiled with:
> gcc -o sleepsome sleepsome.c
I'm quite happy to have someone tell me this is a known issue or that I'm doing
something wrong. If I can provide additional information or try something, I'm
happy to do so.
