Problem
=========
When creating a ZIP file with a bunch of files, it seems that
intermediate results are never written to disk until the compression is
complete. Since all intermediate results are retained in RAM, the OOM
killer can strike when the files to be compressed are too large to fit
in memory all at the same time.
Example
=========
$ free -mh
total used free shared buff/cache
available
Mem: 15G 4.6G 7.4G 1.3G 3.4G
9.2G
Swap: 979M 0B 979M
$ du -hs
56G .
$ advzip -ap4 ../recovered.zip *
