I agree with your assessment.. the behaviour certainly seems consistent with
"ps":

$ ps ax -o fname
[...]
udevd
hald-add
wpa_supp
[...]

It sounds like there's a bug in 'mon' in that case, it probably shouldn't be
using "fname", or at least be expecting it to be truncated.

The value returned by Proc::ProcessTable also includes "exec", the full path
to the executable (available for root and the owner of the process). It may
be better if mon used that, if possible. This would also avoid a process
with the same filename (but different path) from matching erroneously.
