Actually, you're wrong on all levels.
First: It's perfectly simple in Java to create a binary sort that sorts
all arrays that contain objects; so wrong there.
Secondly: The bug has nothing to do with static typing (I'm guessing
that's what you meant. Both Python and Java are strongly typed). The
You can gain substantial speed-ups in very certain cases, but the main
point of Pyrex is ease of wrapping, not of speeding-up.
Depending on what you're doing, rewriting in Pyrex or even in C, using
the Python/C API directly, might not gain you much.

Well, it seems you can do:
parser = elementtidy.TidyHTMLTreeBuilder.TidyHTMLTreeBuilder()
parser.feed(your_str)
tree = elementtree.ElementTree.ElementTree(element=parser.close())
Look at the parse() method in the ElementTree class.

It doesn't think you're on an intel box, it thinks you want to compile
universal libraries, since you installed a universal python.
The problem is likely to be that you haven't installed SDK's for intel
as well as powerpc when you installed Apple's Developer Tools. Do that,
and it should work ...

How much you gain by starting threads is also determined by what you're
doing in those threads. Remember (or learn): In CPython only one thread
at a time can execute python code, so depending on your task threading
might gain you little. If you're doing I/O or calling functions written
in C (and if
Okay, so the reason what you're trying to do doesn't work is that the
readahead buffer used by the file iterator is 8192 bytes, which clearly
might be too much. It also might be because the output from the
application you're running is buffered, so you might have to do
something about that as well.
