TCPServer crash on shutdown

[kbriggs]

I managed to get one crash on shutdown today while running in Debug mode. It left the main VCL thread running along with a few of my own (as expected), the two TCPServer listening threads, and a few Kernal threads identified as "ntdll" in Process Explorer. As before, an End Process killed everything except the main VCL thread and a reboot was required. I'm not all that familiar with the Delphi debugger. Is there something else I should be checking on the next crash?
