[nginx] svn commit: r4501 - trunk/src/os/unix

[mdounin at mdounin.ru]

Author: mdounin
Date: 2012-02-28 11:40:18 +0000 (Tue, 28 Feb 2012)
New Revision: 4501

Log:
Added msleep() on reload to allow new processes to start.

This is expected to ensure smoother operation on reload (and with less
chance of listen queue overflows).

Prodded by Igor Sysoev.
