Why?  I found this greatly improved performance.  I have a cron job
that copies the bayes db files over to a physical disk once every
day so there is no danger of losing the entire database if the ramdisk
would suddenly go away.

On my machine:

/dev/ram0               483886        46    458840   1% /var/spool/MIMEDefang
/dev/ram1               483886    132675    326211  29% /var/spool/bayes
