Yes, I would like you to send me the Cygwin DLL.  I downloaded the most 
current snapshot.  The benchmarks that I am doing don't seem to drop any 
tables, but just in case....
It seems that the problem that I was seeing with the handles has indeed 
been fixed.  Was able to run a 20 user benchmark yesterday. This takes 
around three hours.  The throughput seemed to be at least in the 
neighborhood of RedHat 7.1 Linux 2.4.2 kernel. (1100 TPS on a random 
read-only AS3AP query).
I am currently running a 1-100 user TPC-C benchmark.  This will take a 
couple of days to run.  Will let you know how it turns out.

Thanks
