Hi Holger,

let's collaborate on this. You and I and lots of others want this to be done. But in fixing the below bug my priorities are to

a) deliver a fix promptly

b) write the code so that either kqueue or epoll or select will be used based on HAVE_KQUEUE & HAVE_EPOLL defines

So if I deliver a fix don't think that I'm against having a proper event-driven or idling VM, I just don't have it in my head yet and want the bug fixed and kqueue/epoll available asap.

Dear Eliot,

> Fabulous, thank you! replace the self halts with e.g. self assert: (clientSocket dataAvailable = (clientSocket readSemaphore excessSignals > 0)), and we even have a test. I have work to do tomorrow but hope I should be able to debug this soon. I'll add kqueue and epoll support when I fix it.

before going to kqueue, could you have a look at my hack to create a completely idle VM? Once the VM has moved to kqueue it seems one can not get a SIGIO for the "kqueue descriptor"[1] itself and I don't know if SIGIO remains working for the individual file descriptors.
