[antlr-interest] multi-core usage

[Loring Craymer]

Language processing tends to be single threaded--token sequence matters--and ANTLR generates single thread recognizers.  To take advantage of a multicore/multithread environment, the usual approach (excluding server apps) would be to use the recognizer as a task dispatcher that spawns threads according to recognized (from the token stream) semantics.  There are server applications where multiple recognizers are spawned, one per connection.

multi-core usage 

I have curiosity question.  Can ANTLR take advantage of multi-core processors. 
The only place where I can think it would be possible would be in the lexer where 
you might be able to apply one file per core to be tokenized.  Has anyone tried? 
Again, just curious.
