(It's a dumb question 'cos I don't have NetBSD up and running yet)

wrt the NetBSD virtual memory system:

Does it support all the semantics of mmap(2)  as per SunOS 4 ?

I'm particularly interested in the ability to MAP_SHARED, so
changes to mapped files get reflected in the filesystem.

Also the ability to use mprotect(2) to map regions readonly
and reissue mprotect(2) calls in a SIGSEGV handler, based in
the sigcontext info (faulting address).

Finally are msync(2) and madvise(2) implemented?

(port-sparc alias followups are fine)

TIA
