You need to have the translator managing the directory in which the
file is created (either directly, or as a subdir of the translator), and
intercept the dir_lookup call with the CREATE flag.

I am not sure if you really want to do that, but that's how it could be
done.

Why shouldn't it dump into the CWD of the task, at least for some things,
like user's tasks.  And why shouldn't crash directly create an appropriate
filename?

I don't see how the translator could know about that it is proc crashing.

hostmux mux'es hosts.  It does a lookup on the hostname to check for
equality (like, looking up localhost will return the same node as
127.0.0.1).

Usermux does a password file lookup to check for equality, eg looking up
root and 0 will return the same node.
