I thought that reusing pexecute for this was a really clever idea, but
I'm a bit worried about it.

How do we plan to get input out of the pipe, at the end?  Do we use
pex_read_output, and then read from that file?  If so, I'm not sure how
we can gracefully select() on it, and that means it won't fit well into
the GDB event loop.

And that's even ignoring the issues presented by Win32 select.
