Unfortunately _c_urlarg.so is generated, so:

{{{
>>> from twisted.protocols._c_urlarg import unquote
>>> unquote("""")
Traceback (most recent call last):
  File ""<stdin>"", line 1, in <module>
MemoryError: out of memory
}}}

When running a twisted web server, there's a nasty CPU loop around line 122 of twisted/web/server.py. I guess other defects might occur so the easy workaround os to remove the _c_urlarg.so file.

Everything else seem to work like a charm on AIX (with python 2.6 from http://www.perzl.org/aix/index.php?n=Main.Python)"	defect	closed	normal		core	fixed		spiv exarkun	branches/portable-c-4142	spiv
