No, /tmp is local on magellan only, the terminals don't even know wmii is
running, they are just X servers. All X clients, including wmii, run on
the server. The only thing different about /tmp is that it is a tmpfs
(i.e. dynamic RAM filesystem). Here is the relevant contents:

But the good news is that I managed to catch one of the locks up in the
act with strace. I have attached three files:
'okay' that shows the successful processing of 'Key Mod1-Left'
event. The last event before the freeze.
'froze' that shows the frozen processing of 'Key Mod1-Left' event. The
event that was never recovered from.
'wmiirc' is my current wmiirc script, pretty basic.
Hopefully the strace will tell you want happened. I have the history of
the entire run of wmiirc from shortly after startup until lockup a day or
so later, but it is rather large. I will send it only if it you think it
would be helpful. Thanks!
