Mike, this kind of description really gives me the shivers.  It sounds
like papering over problems wherever they randomly get exposed, thus
actually hiding bugs rather than fixing them.

It may be just your choice of words, but don't make it harder for others
to track down bugs that you don't know the real cause or fix for.  We
can't really hope to find anybody more skilled at finding a bug than you
are skilled at hiding it.
