NOTE: Setting safe=>1... with masked signals does not seem to work.
The problem is that the masked signals are not masked, but when
safe=>0 they are.
If you have an application for safe=>1 and can come up with
a test that works in the context of this module's installation
please send me a patch to safe.t that tests it.
See the block below this one... which if executed would test safe mode
with masked signals... it is a clone of part of mask.t that proves this
is broken.
