With the majority of real time applications, only a relatively small part of
the code is critical.  The beauty of C is that the rest of the code can be
written quickly and reasonably efficiently, and time critical sections can
be written in ASM.  OK, this loses (or at least reduces) the portability of
the code, but to be honest, how often do you port your washing machines
controller code to your cars ECU? :o)

You *can* write deterministic code in C, but you could be shooting yourself
in the foot as it is quite likely to be more difficult and time consuming
than using ASM (e.g. having to refer to the compilers ASM listing and then
tweaking the C code).

You seem to be a little "anti-C"?  If you work in a market where time to
market is probably the single most important factor, then you'd really see
the benefits.
