CVS is horrendous when sharing working directories.  I
think it has something to do with file ownership and
possibly permissioning.

One can view working directories as virtual branches. 
If one has a working directory per task, one can
separate each change set from the others.  So, my
usual advice is to have one separate working directory
for each task or change set (and thereby use a form of
the Branch Per Task Pattern as described at

Since you're using Apache/Tomcat, it shouldn't be too
difficult for each developer to have their own web/app
servers running and pointing to their own working

Going back to "reserved locks", the patch has been
renamed to the more appropriate "advisory locks"
1. It's up to the users to place advisory locks.
2. Users can override advisory locks.

whereas, IMHO, reserved locks are forced by the server
and cannot be overridden by the user.
