Except that the implementation is incomplete. And worse, some functions

such as sem_init() do exist but don't work. Earlier versions of zita-

convolver also required sem_getvalue() which doesn't exist or doesn't

work, I don't remember.
Having to do all of: destroy a sema, create a new one in the filesystem

(which requires unique names), open then unlink the new one, just to

reset its counter to zero is too much a hack for it to be acceptable.

A world of exhaustive, reliable metadata would be an utopia.

It's also a pipe-dream, founded on self-delusion, nerd hubris

and hysterically inflated market opportunities. (Cory Doctorow)
