hi Clement,
I was watching your nice talk on Pharo Optimizing JIT Internals. At 14:40 [1]
you mention VM call-back to Scorch DNU-style. I was just curious how that might affect the jitter of the DelayScheduler waiting for the timingSemaphore set by "primSignal: timingSemaphore atMilliseconds: millisecondNextTick"
to be signalled by the VM?
cheers -ben
P.S. Later when you say Sista will be an optional VM - curious whether Sista might be switched on/off from within the VM? or just a command line flag? or an actual different VM (which adds complexity to system management).
