This might be related to lib9, because nearly every libc call of
Plan 9 apps ends is wrapped in the Unix environment by lib9.
Anyway, in 9base I linked everything statically and the
performance gain was fantastic (however 9base didn't contained
lib9* stuff, because that depends on libthread, which is not
very portable, e.g. amd64/ia64 had serious problems with p9p
(dunno if that has been fixed in the meantime).

I saw a p9p discussion in the IRC. Actually I came to the
conclusion that Russ did it right not to modularize the beast.
The current source tree is pretty much similiar to the original
Plan 9 source tree, that's why p9p is a rather monolithic source
tree and cannot be modularized easily. On the other hand this is
also the reason why I think depending on any bits from Plan 9 is
crap, because you depend on p9p in the end at least - which only
few people really want to install... Thus p9p is a bad default,
but a great option.
