Copyright protects the way an idea is expressed, not the idea itself.
If Linux had a better entropy collector than OpenBSD, the OpenBSD folks
would study the Linux version.  They'd learn how it works, they'd learn
how it was designed.  The Linux developers would probably help them out
in this.  Once the OpenBSD folks knew exactly how the Linux collector
worked and why, they'd go off and hammer out their own version of the
Linux collector.

It wouldn't take them long.  The hardest part of programming is
understanding the problem and how the solution you're writing interacts
with it.  Once you've got that down, the code almost writes itself.  It
comes together really, really quick.

IANAL, if you're doing serious software development talk to your own IP
lawyer before you take this seriously, etc., etc.
