|
|
* tagged transaction is appropriate to prevent simple tag
|
|
* starvation. Since we'd like to ensure that there is at least
|
|
* 1/2 of the timeout length left for a starved transaction to
|
|
* complete after we've sent an ordered tag, we must poll at least
|
|
* four times in every timeout period. This takes care of the worst
|
|
* case where a starved transaction starts during an interval that
|
|
* meets the requirement "don't send an ordered tag" test so it takes
|
|
* us two intervals to determine that a tag must be sent.
