If that is true, then there has to be a bug somewhere...
I might not have tried on 3.2 with virtualenv, but it doesn't take
anywhere near that time normally, and this is not a normal runtime at
all. When we are talking about 2to3 being slow here we are talking
about it taking 10 seconds to install a software that would have taken
under a second to install on Python 2. (Yes, I'm thinking of
Distribute, I just checked. ;-) ).
