why are dlopen flags different between 1.5 and 1.5.2?

[Bill Janssen]

After a fair amount of grief, I found out that while Python 1.5
specified RTLD_GLOBAL in its call to dlopen (in Python/importdl.c),
Python 1.5.2 does not.  Is there any particular reason to change this?
To be compatible with Java?
