Actually, if you have IDLE in the default setup on Windows and you 
right-click something to edit it,
IDLE doesn't open a subprocess each time a script is executed, so it 
will keep the imports in between runs of the program.
I.E. if I type "import math" into the IDLE interpreter, I can then make 
a file with the contents
#---- start

print math.pi

#----- end
and it will work.
just thought I'd mention that.
