commit 458231d178c7c98798c653f574b6aab839637bc1
Author: Raymond Toy <toy.raymond at gmail.com>

    If a process is not schedulable because it has no run-reasons and/or
    an arrest-reason, destroy-process doesn't take effect.
    Destroy-process sets process-state to :active to try to ensure it gets
    the interrupt, but it also needs to clear process-%arrest-reasons and
    push something on process-%run-reasons.
    
    Patch from Paul Foley.
