This means that its faking the atomic increment/decrement etc functions
with a spinlock, but they can still be accessed non-atomically if the
variables are altered behind the back of the "atomic" functions.

To shut this up you need to implement s390-specific atomic functions in
atomic.h; there already are x86 and sparc versions there to crib from.

These are showing up a real bug somewhere.  The value you are passing to
the Seek internal call in metadata/file-io.c is bogus.  It could be
because the value has been marshalled incorrectly.  This particular
symptom has shown up a lot - try searching bugzilla to see how it has
been resolved before.

http://bugzilla.ximian.com/show_bug.cgi?id=30035 seems to be the only
one I can find and it doesnt give any details on the fix,
unfortunately.  You may be able to cross reference CVS commits though.
