[PD] linux - faster load first time

[Kevin McCoy]

I notice this not only on Pd but on most programs... gnome-terminal
eventually starting taking so long to start up the first couple of times
that I gave up and started with xterm, for example.  Firefox takes a long
time as well and I am using that every day...
