This is absolutely something we have on our radar, but we don't have
it implemented yet. It is especially complicated if commandX()
happens to run C/C++ code. Then the signal handlers in Python won't
do a thing. To get that to work, you need:
1. Another process on the same machine that send OS level signals.
2. The author of the C-code must use a macro to install the right
This becomes even more complicated if MPI is involved. This that
said, Fernando has thought quite a bit about this before and we plan
to eventually work on it.
