First off, you filed this against -386, which is not SMP, so I hope that was a mistake and you meant -686 :)
Second off, an application (multithreaded or otherwise) is not guaranteed to utilize more than 1 CPU. It's possible that other processes running are using 1 CPU, while the app is left using the other even for both of it's threads.
I haven't reviewed the code, but it's also possible that it just isn't allowing itself to run as expected. Maybe one thread finished even before the other starts. Who knows.
I really don't think this is a bug. I believe you just aren't getting the results you expect, even though those results are correct.
** Changed in: linux-source-2.6.15 kernel-image-2.6.15-19-386-di (Ubuntu)
Binarypackagename: kernel-image-2.6.15-19-386-di => None
Status: Unconfirmed => Needs Info
