I understand the "quick POST" trick w/CS, but bypassing WAIT? I can see how that would work for something like waiting on I/O completion, but for trading control back and forth, I think it requires (for example) an auxiliary counter (and CDS to update both the ECB and the counter simultaneously). Am I missing something?
Stated as simply as I can: If the POST bit is already on, why call the WAIT service in the first place? All it's gonna do is immediately return.
