Subject: GPL code contamination?

If I were to look at GPL'ed code as the Linux kernel to get an inspiration
how to implement a feature under NetBSD, but would neither cut/paste it nor
try to adapt it to the NetBSD kernel, nor base my solution directly on it,
would I contaminate the NetBSD kernel if I do something similar?

More specifically:
Say I'd want to improve some aspect of the NetBSD scheduler, and reviewed
the Linux scheduler in this respect, and implement a similar data structure
or algorithm within NetBSD without copying or breaking Linux' copyright,
would it be acceptable? It would be a reimplementation at most, if not only
an influence on the final design?

Would it be legally problematic because of a GPL->BSD incompability? Would
it be morally bad? Would it be accepted by the NetBSD community? I know the
other way round happened, especially FreeBSD->Linux, especially since there
is no problem in BSD->GPL.

What's your opinion on the issue?

With kind regards,
Oliver Korpilla
