Yeah, that is an acceptable worst-case scenario.

I don't do anything to ensure it isn't in use. My startup script
copies the latest backup over to the ramdisk after creating it, and so

haven't had an issue.
The other performance boost I got was to specify noatime for the var
filesystem, where sendmail's spool dir resides.
