2.2.0-pre4-ac3, heavy load and file go missing?

Something _really_ odd just occurred. I can't see how it could be a
kernel problem, but I'm stumped as to how it might have occurred.

I wanted to see how well the VM under 2.2.0-pre-4ac4 held up so I did
a make -j bzImage and let it rip...

I left it for about 5 minutes until it was well an truly trashing
(only 96MB of ram available) and then ^C a few times.

Anyhow, it probably took another 5 minutes before I got the prompt
back, and during the build I got lots of `Unable to load interpreter'
messages, etc.

No big deal... the box recovered and all is happy. So I `make clean'
and just a regular kernel build... only doesn't work. Kernel build
failed because some (header) files are missing, but they were there
before the make -j build (I'd built four or five kernels since last
patching it, trying to fix the 3x59x driver).

I assumed it might be ext2fs corruption, but that doesn't appear to
be the case (e2fsck shows nothing).

It appears for some reason, whilst the system was thrashing, some
files were deleted -- but I can't figure out how this might have
occur.

Anyone got any clues on this one? Its a bit worrisome when under load
files start disappearing without any trace....
