There's a problem which I think will affect all unixes: if two copies of 
lhelp are fired up with the same parameters, the first one that 
terminates knocks out the unix-domain socket and the second one will 
bomb when it tries to do the same.

The solution I've used for this in the past is to append a PID, it does 
mean though that something has to look for and delete "orphans". I'd add 
that my preference is to put things like this in the user's home 
directory if possible, since that implicitly limits the possibility of 
clashes on a multiuser system.
