I'd guess it's a filesystem problem, where a file's
timestamp spontaneously changes even though the file
itself has not changed.  I had thought those bugs
fixed long ago, but maybe not.

Could you please start by trying the attached patch,
and then see what gets sent to stderr around the time
of the problem?  That might help us work around the
problem better than the old code did (it introduced
some race conditions).
