Nice to hear! That's what I try to tell people who are asking for the right type theory book or the right dispatch method or whatever before even having a look. It's the same old problem solving; and here are always multiple solutions, each with it's own set of compromises. Claiming the one true way of doing anything related to software is delusional. We're barely scratching the surface.

Edit: While we're here; may I ask how you break out of the dispatch loop? Do you test an end-condition on each iteration? If that's the case, the longjmp trick might be worth trying. The condition will mostly be false, so it might make sense to pay more when it happens instead. You may find the essence of it in sgl_run at the bottom of sgl.c [0].

For what it is worth my JITter uses mprotect from other thread to change page permissions to generate an exception to break out of JITted code. Same would work for dispatcher as well.

The advantage is it's completely free performance wise while the code is running. The need for signal handler is less awesome.
