Now. There is one more issue. Seems that on faster computers and/or=20
Windows 7 (the Win32 thing I have tested on a HVM Xen machine with=20
Windows XP) the os.rename is too fast after fp.close() and generates the=20
same Exception. The code follows:

curl.close()
fp.close()
os.rename(tfile, actualfile)

Where, tfile is the .part file, actual file is the real destination, fp=20
was opened with open(..., "wb") and the descriptor passed to curl.

I have solved the issue with self.msleep(10) - msleep is a method of=20
QThread. But I don't think it's an elegant and normal solution. Did=20
fp.close() is delayed, or? I mean, I don't want to rely on a "sleep" in=20
order to workaround the access issue.

On this issue there is no more process spawn, nothing, just the=20
downloader thread and the main window. And the access denied appears at=20
random time.
