Each user has his own CVS working directory, right?

Where do you make the "chdir" to the working directory?
In the External Method or in the external process?

When you do it in the External Method, you get non-deterministic

	The working directory is a process resource shared
	by all threads.
	When the working directory is modified concurrently
	in different thread, the resulting working directory
	in undefined.
