Long time for first plot on Windows

[John Swensen]

I have a student who has started using Octave for some of our simulations and ran into the problem of the first plot taking a long, long time to show up described at

http://lists.gnu.org/archive/html/help-octave/2015-12/msg00159.html

and

Apparently, plotting works fast and fine after the initial 2 minute wait for the first plot to show up.

I tried to search through the bug reports on Savannah to see if one matches, but I couldn’t seem to find one. 

Is this a known issue?

Does it have a workaround?

If not, I will submit a bug report, but wanted to check in here before cluttering the Savannah bug tracker even more.
