[Bug 1051935] Re: Fails with SystemError when too many files are open

[Jason Conti]

Thanks Barry, I added both of those to python-apt at:

lp:~jconti/python-apt/closeable-cache

with fixes for both gdebi and oneconf:

lp:~jconti/gdebi/closeable-cache
lp:~jconti/oneconf/closeable-cache

Stuck with del self._records to clean up the file descriptors since I
took a look at the apt code for PackageRecords and it follows the usual
C++ idiom of closing files on destruct.

While debugging the gdebi code I found another way to reproduce this
specific bug, just continue Refreshing (ctrl+r) until the eventual
SystemError, though I'm not sure how one would run into it in normal
circumstances.

Doesn't help with the memory issues listed in bug #894314 but maybe
oneconf can do some explicit garbage collection to keep memory
reasonable.
