Memory footprint issues when unzipping large archives

[GoogleCodeExporter]

When unzipping large archives, the footprint of -[ZipArchive 
UnzipFileTo:overwrite:] can become very large, because there are autoreleased 
objects created for each individual file during the unzip.  These don't get 
released until after the call returns, when the autorelease pool is next 
drained.

To fix the problem, add another pool inside the do{}while in -[ZipArchive 
UnzipFileTo:overwrite:] :

    do{
        NSAutoreleasePool *internalPool = [[NSAutoreleasePool alloc] init];

        if( [_password length]==0 )
...
        ret = unzGoToNextFile( _unzFile );

        [internalPool drain];
    }while( ret==UNZ_OK && UNZ_OK!=UNZ_END_OF_LIST_OF_FILE );

Has this fix been rolled into the source? If not, any chance I can get this 
fix? We are running into this ourselves and this fix would help us greatly.

Thanks!
