I upgraded my 0.9.3 installation to 0.9.4, and forgot
to set the new variable 'cvsroot' in lxr.conf
Clicking on any of the lxr links after that spawned
many, many perl and diff processes that never ended.
The only way they would end would be to restart the
Setting the 'cvsroot' variable fixed these problems.
I believe the solution to this problem is to add a
check in lib/LXR/Files/CVS.pm to see if the variable
'cvsroot' is defined in the configuration, and, if not,
to die with an error message.
