I would the first step would be to have some means to measure the
performance of our parsers, especially yacc.c.  Then I would try to
modify yacc.c so that the traditional yyparse is provided in terms of
a push parser.  If there is no notable performance loss, then that's
the way to go IMHO.  Otherwise, it will be m4 fun time.

There are good candidates for the benchmarking in the torture.at part
of the testsuite.
