Re: UUIDs generated using ossp-uuid on windows not unique

Using the dll from the link that Hiroshi posted actually fixed v1 in my
case (though perhaps it's just an unrelated side-effect caused by using
a different random number generator which might be slower???). Thanks!

Anyhow, I would have expected v1 to work fine in this case too as the
ossp-uuid implementation has provisions for preventing overlapping ids
when they're generated in rapid succession. And, as I was only
generating about 1 uuid/ms, I didn't think that would be pushing the
limits of the algorithm.

Thanks again everyone,
Meetesh
