Precautions to not run out of disk space?

Hi,

we recently had a software bug who wrote gigs of data to our database in
a loop and finally filled the whole system.

O.K. we could serverside use a separate partition/storage for the
database directory, but I was wondering is mysql has a feature/option to
set some sort of  "minimum disk free" than stop writing and wait for a
sysop to check?

Would be nice, as other software can do this already ....
