Erik, what do you think about the strategy of automatically setting the
cleanup flag when svntest is run with a RAM disk?
[[[
Improved RAM disk usage instructions for svntest, and general info.
* www/faq.html
Added much more information about testing on a RAM disk.
* tools/test-scripts/svntest/svntest-run.sh
When a RAM disk is in use, automatically flag Makefile test targets
for cleanup to reduce overall RAM disk size. The trade-off of
increased I/O should be quite reasonable, considering that the I/O
will be against memory, rather than physical disk.
* tools/test-scripts/svntest/README
Added a quick blurb about what "svntest" actually is/does. Altered
RAM disk instructions to match up with new svntest-run.sh cleanup
flag behavior, and updated pointer to FAQ URL.

I think 700MB RAM disc size is not reasonable, so, yes, I think that
bringing it back to around 50-60MB is a good idea.
Note that this does not destroy any data, since the RAM disc is
unmounted at the end of the script (thus eliminating any possibility
to check any test data left behind).
bye,
Erik.

Erik came up with a good patch along these lines. I'm merging our
patches together, and will re-post. Thanks for the feedback, Jani.

Please provide it as a flag. I run svntest framework time to time by
hand or by external scripts, and I then definitely like to poke around
with test repositories.

Something like:
+ CHECK_ARGS="$CHECK_ARGS $CHECK_CLEANUP"
and svntest-config.sh:
+ CHECK_CLEANUP="CLEANUP=1"
Thanks,
