[Python-Dev] Interning filenames of imported modules

I have a question about the following code in compile.c:jcompile (line 3678)

		filename = PyString_InternFromString(sc.c_filename); 
		name = PyString_InternFromString(sc.c_name);

In the case of a long-running server which constantly imports modules,
this causes the interned string dict to grow without bound.  Is there
a strong reason that the filename needs to be interned?  How about the
module name?

How about some way to enforce a limit on the size of the interned
strings dictionary?
