Asking the obligatory question :) : Why use a separate process for
this very task in the first place? Are there locking issues that are
very hard to solve when doing the CVS handling in-process (i.e.
launching the cvs process from inside cervisia, not using a second
proxy process) ?

It seems to me that there is a lot of communication between the cvs
service process and cervisia as client, which is where things get
complicated with DCOP (how to recover when the process dies?) .
Imagine how simple the code in cervisia could be if you could deal
with CvsJob C++ objects directly.

Just a though. Feel free to ignore :)
