So would I - but there would be hundreds of thousands of calls out of the
parse; to wrap these in timvar would be prohibitive. One approach I thought of
could be to do sampling by setting regular interrupts based on timeouts and
check if the IP pointed into bison (i.e. a kind of poor man's gprof), however
it would be difficult to do this portably.
