Mmh, I've certainly not seen this under *nix, but I know that win32 has very 
different locking behavior than *nix, and I'm afraid I'm not sure what the 
solution should be.  Any win32 experts who can suggest a good solution?

I should note that %run is little more than a safe wrapper, with nicer 
exception handling and all the fancy namespace switches, around the builtin 

The first thing I'd try is to see whether using a plain 
execfile('yourfile.py') causes the same behavior.  If it does, I'm afraid it 
won't be easy for me to help there, unless you can find a flag or trick to 
cure the problem manually.  If you do, by all means please post your solution, 
and I can stuff it in the right place in the ipython library.
