It might get constrictive after a while.
please talk to John and Thomas about GTOD interfaces. Right now the solution used by the latency tracer is working out pretty OK - but if something better comes along i can use that too. It's not a burning issue though, unless you know of some bug. (i'm not sure what you mean by it becoming constrictive)
