i don't think moving signal handling into a random module makes sense.
the main loop should be responsible for this business.  i.e. where the
code is now (or in catalyst._main).

if the only thing you want to handle is clean up of mounts, then we
should be looking at mount namespaces instead.  unlike other namespaces,
support for mount namespaces has been around forever and can't be turned
off in the kernel.

the releng repo deals with this by running everything through unshare.

snakeoil already includes namespace support.  i'll send a patch.
