More proof why I should leave such low-level realtime stuff to the
experts. :-) Thanks.
Here's a derivative question... is there such a thing as a realtime OS
that is usable by application developers who don't want to have to think
at such a low level? Conversations about the "evils" of using conditional
code, for example, make me as an application-level developer lose
interest.
