Cygwin b18 currently only supports 100 processes on the overall system
(not under a session leader).
I understood this limit will be the same in b19.
If you're compiling cygwin.dll yourself, try to raise the value of PSIZE
in winsup/winsup.h.
If you're using coolview and you want more than 16 telnet sessions
(which is the current limit), try raising
NTTYS in winsup/tty.h
