I've tested the CVS source 20031217 10:00AM (GMT+1) to see if fork/spawn
works on Multi CPU (4 Xeon) with Windows 2003 Server (see old message
about it in the mailing list). Unfortunatly It doesn't !
Below a test script, use it by running run_t.sh. After some time (< 1
minute) one or more of the 5 sub-shell stop. This batch works perfectly
using a single P4 cpu on Windows XP !
Thanks in advance, Philippe.
PS 1 : 4-5th attempt to send a mail to cygwin@cygwin.com using three
different mail account, gmane newgroup ! Anti-spam ? :(
PS 2 : Vital for me that this works before end of the month !
