[Bug 591100] Re: autofs5 eats the cpu if you have large groups

[Joel Ebel]

SRU team, as mentioned, this bug causes significant delays in
automounting when your primary group is large (thousands of users).  The
bug has been addressed by increasing the group buffer size geometrically
rather than linearly.  If the primary group is small, there will be no
change.  The patch I originally provided still applies to the version in
Lucid.

TEST CASE: Your primary group should have thousands of users, and you attempt access of something in an automount managed directory.
Expected result:  It succeeds or fails quickly.
Prior to this fix it will take several seconds.

There are no expected regressions from this patch.
