I'm not clear on how the parameter to this statement is used. I've read a couple different descriptions about this and I get the impression that the parameter is the interval in which a blocking check is performed. But I've set up blocking situations to test this, and sometimes it picks up the block and sometimes it doesn't. It seems to depend entirely on how long the block is allowed to go on.
If the parameter does represent the check interval, then each time it fires, how long does it keep looking for blocks before it stops checking?
I guess I don't really understand how this works. Can someone clearly describe how this is used?
Thanks.
