Is there another way to "deallocated" these colors from the color map?
If it requires a cron job or something else I am fine with that, it's
just that we typically don't restart a zephyr session for a week or
more. On Solaris 2.51 we had full use of colors and seldom shutdown
zwgc sessions (somebody may created a mechanism for de-allocation on
colormap our end and I am not aware of it).
Thanks for the very prompt response BTW!!
