that shouldn't be a problem in most cases...

JAM has its own special lock method, too... i forget which file it is but
there's a region that is locked during writing... reading is allowed by all...
if something else wants to write, it tries to lock the same region... if it
cannot, which it should not because of the existing lock, then it should delay
and retry the lock for some period of time... if it gets the lock, then it can
do its write... otherwise it either aborts or asks the operator what to do...

maybe, maybe not... depends on the config, i guess...
