Yes, qio.readline() is about the most frightening function in the Python
universe now <wink>.

I compiled it for Win32 (btw, "mode_t" was not defined, & there are about a
half dozen warnings about mixing signed and unsigned ints), with
optimization cranked up.  Under Win95 it was between 2-3 times as fast as
1.5.2 Python doing a native readline() loop over an 11Mb text file.  It's
hard to believe that MS's grudging implementation of stdio is that much
better than glibc's, so not sure what to make of this -- possibly that
*nothing* can run really fast under Windows <0.9 wink>.

Nice work!
