Apache Httpd < 2.0.49 : listening socket starvation

A starvation issue on listening sockets occurs when a short-lived connection on a rarely-accessed listening socket will cause a child to hold the accept mutex and block out new connections until another connection arrives on that rarely-accessed listening socket. This issue is known to affect some versions of AIX, Solaris, and Tru64; it is known to not affect FreeBSD or Linux.
