/var/log is definitely a "mostly write" directory, but I wouldn't
ever classify it as "write heavy".

Unless you are trying to perform thousands of concurrent writes
and/or log file creation/removal operations every second to
/var/log, then putting a project quota on that directory is not
going to cause you any sort of noticable problem.

Cheers,

Dave.
