Have you tried ctrl-t? This will send SIGINFO to the process which
causes the shell to print out some information about the running program
(and if the foreground program knows about the signal, it can print out
some useful diagnostic info as well, like fsck and dd do). It sounds
like something is waiting for input or otherwise wedged, and ^T might
tell us which command and what it's trying to do.

Additionally, the output of ps ax -d (show process trees) would be
helpful. This should also show what mergemaster is waiting on.
