The FHS constructed /usr such that it can be mounted read-only.  So  
/usr/tmp should not exist.

The preserving action of /var/tmp makes it a special place that should
be used with care.

/tmp or some subdirectory of the user's home directory are the main
solutions for temporary files.  Though some systems have /tmp only with        
restricted writing access.

Fortunately groff defines the environment variable $GROFF_TMPDIR for            
all cases.
