What's happening is that the return value passed from the server back to
your client process has gummed up the works for RPC. The next call you
make runs into the gum and clears it up. How's that for a high-tech
answer ;) This would be a bug if it occurred in Windows 2000 and/or
Windows XP, but it seems to be fixed in the more recent products.

Your thread isn't taking up any resources while it's hanging on a call
from your client process into your MTX.EXE process. So there's no real
gain in killing it at that point. Someone else suggested "killing" the
process by setting a flag that will cause it to exit right after the
long-running call returns. That's a much cleaner solution. If you're
concerned about components hanging in MTX.Exe, fixing the problem there
(by aborting "hung" components) will be safer for you.

Unfortunately, async com isn't a solution for you even in later
operating systems, since you can't combine async com and COM+ services.
