[Pkg-mailman-hackers] Bug#440323: Ability to change the niceness of the mailman process group

[Peter Rabbitson]

Package: mailman
Version: 1:2.1.9-8
Severity: minor
Tags: patch


My mailman installation is quite large and it is really desirable to modify
the priority so the server can do something else in the meantime. This patch to
the init script does precisely this. Feel free to include in the official 
package if you find this useful.
