these errors are getting very frequent, I know that Gregory is seen them 
very often.

While debugging and enhancing GWorkspace these days, I quit and 
restarted it very often and I got lock problems a frequent amount of time.
It usually was one of the spawned daemons (e.g. fswatcher), Recycler or 
even GWorkspace itself.

It can however also happen when opening and closing one application 
itself, e.g. ProjectCenter.
I am pretty sure Gregory was seeing it too with PC yesterday.
It does not occour everytime of course and this makes it difficult.

Today i got an error and exception (coudln't copy the error because 
everything crashed when I tried to copy the string)
"cannot remove the lock file because the lock file does not exist."

This looks like a lock cleanung up the lock file, it is removed and 
gives an error. It was the only GS application I started.

This happens on Windows, Linux, NetBSD...
