* Foreign concurrent calls, handle IO, and all IO actions that directly interact with the world outside the current process all must be yield-points. (in addition to any yield-points implied by the progress guarentee)
If an IO call includes a long period of waiting, we don't only want it to yield before or after it. We want it to allow other threads to proceed during the whole wait. -- __("< Marcin Kowalczyk \__/ qrczak@knm.org.pl ^^ http://qrnik.knm.org.pl/~qrczak/
