Solaris/Sparc/UP.
One writer and three readers ran for 30 minutes on Solaris 10 without
printing anything. The box is an UltraSparc IIIi dual proc, and the FS on
the partition

I'd want to know what results this program gives with different systems.
Please test and reply (but don't bother if someone already replied with
the same OS+result). I expect it to print:
Hi Timo,
It prints the following:

You can forget about this for now. There was one bug in it and with a
couple of changes I can't break it in my own system either anymore.
Wonder why I'm seeing similar problems in Dovecot v1.1 code..

I just wanted to test it using Linux 2.6.21 on my Core2 Duo T7200 running

If there is no output, whats the longest you want us to wait
while it runs? How much do you care about unique OS/arch/cpu/fs
combinations (what factors shouldn't matter)? I assume you want
just one reader and one writer, started in the order listed in
the source?
I currently have it running on

I think if it hasn't printed anything for 15 minutes it's pretty safe to
assume it's not going to print anything.
