I tried this and while IDLE didn't crash, it stalled when running with and
without a subprocess. I then tried running this from the regular python
interpreter and it stalled there as well. This is not a problem with IDLE, but
a problem with pydoc itself.
Steps to reproduce:
>>> help()
help> modules
-- stall --
A blank "Tk" window suddenly appeared, which suggested that something loaded
Tkinter. Digging deeper, the "help" utility in Lib/pydoc.py loads every single
module found on in sys.path in order to get its __doc__ string. This is doing
too much work as the purpose of "modules" is to give a list of available
modules.
I modified "ModuleScanner" in pydoc.py so that loader.load_module doesn't get
called. I set "desc" and "path" do hard-coded strings and now "modules" returns
a list very quickly. A blank tkinter window still pops up, however.
