Incremental counter is not good enough, since the puprpose of the ids is
to differentiate between change records generated from separate
instances of AW, and as such they need to be unique in time and space.

As said elsewhere in this thread, the problem on win32 is to do with the
15ms granularity of the time API, but we cannot avoid it, because the
collaborative stuff will require accurate timestamps. I understand there
are ways in which a more accurate time can be got on win32, and if
someone wants to investigate this to improve the performance of the
UT_Win32UUID class, patches are always welcome.
