This is tclsh8.3.2 and tclhttpd3.2.1, but I don't think this is very
version specific.   One particular standard example is where docRoot
is simply a directory with no html files.   Even if a file transfer
succeeds, we end up with a zombie process.   From the error file:

[07/Feb/2001:20:14:40] sock7 error writing "sock7": broken pipe /testinstall.exe
[07/Feb/2001:20:14:40] sock7 error flushing "sock7": broken pipe /testinstall.exe
[08/Feb/2001:16:26:31] sock7 timeout 
[15/Feb/2001:17:04:14] sock7 timeout 
[16/Feb/2001:06:56:40] sock7 error writing "sock7": broken pipe /marbella
[16/Feb/2001:06:56:40] sock7 error flushing "sock7": broken pipe /marbella
[16/Feb/2001:11:14:36] sock7 timeout
