tdf#125662: disable parallel-zip if the memory...
required to carry it out will cause a breach of addressable memory
limit. This can happen in 32bit OSes, where the physical memory limit is
more than the process addressable memory limit. For example in Win32,
a process can address only upto 2GB.
More specifically, avoid using ZipOutputEntryParallel
which rougly needs twice the memory compared to its counterparts.
