I think the reason this hasn't been complained of too much is
it's generally better to use poll(2) instead of select(2) if your
program can have a lot of file descriptors open. Have the Zarafa
developers considered offering a poll()-based option?
meanwhile, I got the reply that --enable-epoll triggers epoll(2) usage.
However I am already building with that ./configure option and thus it is
not solving the issue. Does it mean there are other select(2) overlefts?
