I know what I was thinking, but it doesn't make sense any more.<BR>
I could have sworn I saw a race where the value changed between<BR>
the check and the subsequent read/use.<BR>
That makes sense, in that I don't change the value under a lock.<BR>
But it doesn't make sense, in that the changer should be suspended.<BR>
The check is done shortly after in the C code though.<BR>
There is just one read, and the purported race is gone.<BR>
It should be ok. The one uncertainty on my part is what the HeapRep.FlushState does.<BR>
I looked at, but I didn't follow through as to the other uses of the state it changes.<BR>
