Summary: profile.run makes assumption regarding namespace

Initial Comment:
When profile.run() is executed, it assumes that the local 
and global namespace should be determined from the 
locals and globals for __main__.  In the case of an 
embedded interpreter, this is an annoying assumption.

For instance, I have a PyQt program that has an 
embedded interpreter running as a "debug" console and 
need to profile a little segement of misbehaving code.  
With direct access to all the gui interactively, it seemed 
like a simple task of profiling a function call on one of my 
gui elements, but the namespace in the interpreter is very 
different from that of the main application.

A simple fix is to allow profile.run to be executed with an 
optional dict so the user can give their own namespace.  
A diff -u is attached which accomplishes this.

Note that this problem appears in the current Python CVS 
on sourceforge, but exists at least as early as Python 2.2.

I don't see the issue. Why can't you use

  prof = profile.Profile()
  prof.runctx(cmd, mydict, mydict)

???

This seems like a reasonable request.  The use case is 
uncommon but I don't like having __main__ hardwired in 
the code.  What do you think?

If you want the change, should it be put into Py2.3?

Doh, sorry about that.  Guess I should actually check it after I 
submit...

There's no uploaded file!  You have to check the
checkbox labeled "Check to Upload & Attach File"
when you upload a file.

Please try again.

(This is a SourceForge annoyance that we can do
nothing about. :-( )
