[daip] AIPS - Shared memory ID failure: Lion equivalent of sysctl.conf

[Brendan Reardon]

Eric and Wes -

I edited the permissions on sysctl.conf as you instructed to be,

> -rw-r--r--@ 1 root wheel 111 May 23 13:09 sysctl.conf

After these permission changes, I manually edited kern.sysv as
Wes instructed me to do with sudo with no avail - the values reset once
again after reboot.

As for potentially moving off of shared memory, I am currently reading this
webpage: http://www.aips.nrao.edu/cgi-bin/ZXHLP2.PL?XAS but when I go to
access this "~/.Xdefaults" file that you speak of I am having difficulty.
"more ~/.Xdefaults" yields no results.
