Where could we take user-mode test from?

[cahirwpz]

With more and more functionality exposed to user-space we'd like to have our syscall interface tested for compliance with POSIX.1 standard. There're plenty of tests out there, so let's make a list of places we could take them from:

• OpenBSD regression tests: some of them are public domain, looks promising,
• FreeBSD regression tests: BSD license, obviously,
• NetBSD regression tests: as above,
• Linux Test Project: most tests are licensed under GPL2, so we can't use them :-(

If you find another source of good tests, please post it here. Remember about licensing issues, we can take in public domain or BSD / MIT licensed source code, but not GPL...
