[Vm-dev] [OpenSmalltalk/opensmalltalk-vm] [Win10] [Squeak] High CPU usage in different images for a few minutes after resume from sleep (#537)

[Eliot Miranda]

Hi Christoph,

   the VM maintains a circular buffer of the most recent 256 invoked non-JIT primitives, the primitive trace log. This is sometimes a useful clue to what the VM has been doing up to the point where the primitive trace log (PRL) is dumped.  On Unix the PTL and current stack can be printed on stdout by sending SIGUSR1 to the VM.  If you wanted to dump the PTL on Windows you’d have to work out how to signal the VM.  I’m in no way a Windows expert so I have no idea how to do this.  But if I were in your shoes this is the route I would take.
