This probably isn't a problem any more since the new fixincludes
mechanism is so much faster than before. It is still a problem
on occasion with (at least some versions of) amd and make check.

Open up a second xterm (screen, login session, whatever), and cd
into $srcdir/gcc/testsuite/. The live process with a cwd on the
automounted filesystem will keep the thing from being unmounted
in the middle of the test run.

It was probably a bug in the BLOCK manipulation code, which has
been completely rewritten since.
