This test assumes that there is no debuginfo for getpid -- but in my
case, I have glibc debuginfo installed.  This isn't unheard of for gdb
developers :)

The test would be more robust if you put a new function in a new file
and arranged for that file to be compiled without debuginfo.

Sorry I didn't notice this before.

It seems to me that one of these breakpoints has to be thread-specific
as well.  Maybe the code to set b->pspace should notice thread-specific
breakpoints and allow pspace to be set there.

I'd rather this be done in breakpoint.c than have other modules modify
struct breakpoint directly.
