Very short day :-)

Worse than having to reboot, files (possibly with hours of work) are
lost.  Even if I saved them from MacPerl (or BBEdit or whatever).
Even when in the Finder I made a copy of the saved document.  I
suppose the Finder knew about the existence of the file(s) but didn't
write it to disk, and then crashes along with everything when one (!)
application makes a mistake.  The entry in "Recent Documents", which
is only an alias and now useless, is the only trace left of my file.

On a Unix, I would type "sync" to get all cached data written
physically onto disk.  What would be the equivalent command on Mac?
And where is the shell into which to type it?

It is easy to crash the Mac:
 * turn on the Perl Debugger:   "out of memory !\n" x 12
 * run a demo script from mac:QuickTime
