    Maybe we could get a gcc hack using the __attribute__(())
    mechanism... say __attribute__((no_block)); any routine marked
    nonblocking would print a warning if it called a blocking routine. I
    understand this is a mechanism already build into gcc to support
    various system-dependent hacks...
