dan, apologies for not making this clearer: potentially hundreds of thousands
of file handles will be required.  this patch is NOT production-suitable, you
really do have to bite the bullet and fix wineserver properly.

this patch is for "demonstration purposes" ONLY and it would be a severe bug if
it were included, as it could be used to attack a system through resource
starvation simply by opening hundreds or thousands of NamedPipes and sending
hundreds or thousands of messages on each pipe.

sorry, dan - this is about limitations in the design of wine that simply
haven't had to be tackled up until now: it's now time to deal with them if wine
is to ever progress to the next level of interoperability.
