Currently, it's possible for the
cancel_requested
flag to be cleared without the vcpu being cancelled. This can lead to a call tokill()
being lost. Consider the following thread interleaving:kill()
which setscancel_requested
to truecancel_requested
to false.This PR fixes it by only clearing the flag when the vcpu is actually interrupted.
