// Notes on the use of CRun's m_dwMaxRunTime and m_ftKill fields:
//
// m_ftKill is the time when the job processor thread monitoring the
// job should try to kill the job, if it hasn't already terminated.
// It is an absolute time.  It is computed when the job is launched, based
// on a combination of (1) the duration-end of triggers that have
// TASK_TRIGGER_FLAG_KILL_AT_DURATION_END set and (2) the MaxRunTime set on
// the job itself.
// (1) can be predicted before the job runs, so it is calculated in
// GetTriggerRunTimes() and stored in m_ftKill.
// (2) is a relative time, so in many cases its end time cannot be
// predicted until the job runs.  It is temporarily stored in m_dwMaxRunTime
// when the CRun object is created; but it is converted to an absolute time
// and combined with m_ftKill when the job is launched in RunJobs().
//
// Once the job is launched, m_ftKill remains the same for the lifetime of
// the CRun object, even if the job is killed because of
// TASK_FLAG_KILL_ON_IDLE_END and restarted because of
// TASK_FLAG_RESTART_ON_IDLE_RESUME.
//
// m_dwMaxRunTime is the remaining number of milliseconds that the
// CJobProcessor::PerformTask() thread will wait for the job to terminate.
// It is initialized to (m_ftKill - current time) in CJobProcessor::
// SubmitJobs() and repeatedly adjusted downwards each time the job processor
// thread wakes up.  If the job is killed and restarted, m_dwMaxRunTime is
// recomputed from the original m_ftKill and the new current time.
