Other X related system tunables are NSTREAM, NUMSP, and NQUEUE.
While the X documentation lists suggested settings for system
tunables and pseudo terminals, these settings will not be
optimum for every installation. If you experience problems
such as not being able to open more than a certain number of
windows, you may have to adjust tunables up or increase the
number of pseudo terminals configured. Try increasing NUMSP
first since that is the one related parameter not automatically
increased during X installation.
