Re-loading updated modules

[fileexit]

Hi,
Shouldn't python recompile a module if there is a later version of the
code (.py file)? While i am debuging, i always have to exit python and
delete the pyc before every run, then start it again and import the
modules.  It seems that this is the only way for it to recompile the
new code.

What is going on? is this normal behaviour? I noticed that on both
Windows and linux (Fedora Core 4, and 5 and RHEL 4)
