think if you set just SAGE_TIMEOUT to 20000 seconds, but leave
SAGE_TIMEOUT_LONG at the default 1800 seconds, then the long tests will
just use 1800 seconds.

I was not aware of that.

individual doctests in it.)

the timeout doesn't help much; it's better to then reduce the number of

I know there are exceptions, but normally one can kill the process that's
taking all the ram. If ulimit was set, this should not happen.

GB RAM.
FWIW, that's running Solaris 10 03/2005, so is an almost 6 year old
version of Solaris.
A later version of Solaris, if configured to use the 128-bit ZFS file
system, then I doubt 2 GB would be sufficient. One could always use the
old UFS file system, but ZFS has lots of advantages, but it tends to need
more memory.
