Gnuplot woes.

[Huaiyu Zhu]

I've seen similar behavior on my Linux laptop, probably because the OS does
not write out file promptly (due to apm?).  Experimental result:

for i in range(10):
   g.plot(something)
   time.sleep(sleeptime)
   
works if sleeptime >=0.5, fails if sleeptime <=0.2, and partially fails in
between.

Anybody knows a cure other than sleeping half a second?
