Thank you Art. This clarifies what happened, but not how it happened. 
I used cmd.exe to run telnet.exe and telnet used the cmd's console. 
When the telnet's connected socket received a disconnect signal, 
printed the message and the telnet process died. cmd.exe saw it and 
printed the CWD but then what did it happen? Why cmd died? When a 
process does not allocate its own console presumably duplicates the 
one it borrows from the parent process. So you say that telnet's 
duplicated handle of the cmd's console failed to be cleaned on 
process termination. May that be due to a bug in KERNEL32/CSRSS? But 
still I donn't understand why cmd died.
