You're saying whatever he did made PM *unavailable*? What could
possibly cause that?

Nope, it was a DOS box generated from a DOS Prompt shortcut, modified
to make a full 65536K available to DPMI clients. The call to gcc was a
direct child of the prompt, which in turn was not a subshell from
anything, unless you count Windows itself. Also, earlier use of gcc
from the same DOS box worked. Unless of course, the pest had closed
the DOS box and opened another of a different nature, or had run
something in it and then invoked a shell. The latter seems unlikely,
though.

Surely it doesn't leak when it's *idle*? Someone has to be doing
something major (opening and closing windows, say) for a memory leak
to occur, and nothing automatic was running that does anything of the
sort. Otherwise it really does start to seem like a "watch winding
down", which a computer certainly should not be.
