I have now installed a pristine Fedora core 3, which I presume is with
NPTL. On this I have installed a precompiled Mono 1.1.5 for Fedora core
3. All my test cases, including the one you are refering to, runs
smoothly on both Fedora and my Debian running 1.1.4.

The reason for this, in my opinion, is that the spawned child is getting
instantiated with the parents running environment and in than sense it
replicates the dup function from C with I believes is thread safe. See
documentation below.

/* my example */
Parent: Signing off!
Parent PID: 8740
loke:~/Projects/appserver/fork$ Client running as deamon with pid 8740
Server started

/* example from bugzilla */
loke:~/Projects/appserver/fork/fork-test$ sudo mono fork-test.exe
Starting fork test
loke:~/Projects/appserver/fork/fork-test$ Configuring...
Configured.

Trying telnet - remoting running on port 5605:
[mir at localhost fork-test]$ telnet localhost 5605

Connected to localhost.localdomain (127.0.0.1).
