I believe the failures of speculative tasks come under the normal task
failure situations, and that there isn't really a special status
assigned to these tasks. So yes, if the conditions for speculative is
acceptable in further TT heartbeats + the Task hasn't reported
completion yet, a new speculative task will be launched.
