I've had similar issues with ANTLR sporadically claiming that my lexer 
rules are ambiguous (they aren't unless k=1), and I would hope that my 
development machine isn't considered underpowered (1.6GHz Atom, 1GB RAM, 
running up-to-date Ubuntu and the Sun JDK 1.6). Maybe the default 
timeout should be a bit bigger?
