On a related note, on windows xp + ESS + R 2.9.2, I have long waits when I
run:
browseURL( unitTestOutFile, browser="C:/Program Files/Mozilla
Firefox/firefox.exe")
Firefox is always already open, and sometimes the old test results are
already open too. Sometimes it takes minutes to open up, sometimes using
submit+step in emacs seems to be correlated with this getting this to go a
bit faster (but I can't tell what causes the huge variation in time opening
the webpage)... I'm upgrading to 2.10.x next time I can schedule it on my
work machine.
