Does the poll()ing a shared pipe bug also affects nginx?

[Mark Alan]

Hello,

At the dovecot mailing list there has been a discussion about what
seems to be a bug where, in linux, systems poll()ing a shared pipe
triggers unnecessary context switches.

Does ningx also poll()s shared pipes?

The bug report (from dovecot author):
http://marc.info/?l=linux-kernel&m=129243588809986&w=2
(full patch here: http://hg.dovecot.org/dovecot-2.0/rev/b0ec48006d57)

And the answer from the linux kernel people:
