My guess is that cvsps is using CVS commands to access the test CVS
repository, and that CVS wants to write to the file CVSROOT/history to
log what is being done.  The logging behavior can be turned off either:

* by using the "-R" option when invoking CVS.  This is a global option,
meaning that it has to appear before the subcommand: "cvs -R update"
rather than "cvs update -R".

* by setting the "$CVSREADONLYFS" environment variable.

Apparently -R and "$CVSREADONLYFS" were added in CVS 1.12.1, which was
released in 2003.
