perhaps your issue is having too many things installed?

The laptop I'm working on was decent when new, six years ago, but is now not the fastest thing on the block. It has certainly collected quite a lot of things there (mostly from system packages), but it is probably just one or two things that are spending most of the time (excluding I/O time).

It's interesting; now that I've tried running it a few more times, `help('modules')` on my Python 2.7 is getting down to six or so seconds. (On Python 3 it takes around 0.15 seconds.)

Wow! My Pthon2 help('modules') opens a window titled "Hello from wxPython"!

Python3 behaves well, and both succeed...
