And how many thousand lines of code (including libraries, etc. that may 
have been pulled in)?

I had just this discussion yesterday at work with someone.   These days, 
silicon (even going into space) is much cheaper than people. Sure, you 
could optimize a hand crafted little routine in assembler. Or, you could 
just load up RTEMS, compile your program, link in newlib, etc., and have 
it working in a day.  If you've got 2 MByte of memory, nobody cares 
whether you use 1kbyte or 50kbyte.
