5.2+ stable releases now support parallel compression

please rebuild with mkaurball :)

@leafonsword: xz-git is a package that builds latest code from git repository. Once xz receives a stable release with support for parallel compression this will land in xz package in [core].

xz-git ist pretty reliable for me, though. Did not have any issues in years.

Why official use xz since that xz version doesn't support parallel?

The dependency to sh comes from xz in [core]. Why do they have it?

Parallel encryption and decryption is disabled by default use -T to enable it. From man xz:

-T threads, --threads=threads
Specify the number of worker threads to use. Setting threads to a special value 0 makes xz use as many threads as there are CPU cores on the system.
The actual number of threads can be less than threads if the input file is not big enough for threading with the given settings or if using more
threads would exceed the memory usage limit.

Currently the only threading method is to split the input into blocks and compress them independently from each other. The default block size
depends on the compression level and can be overriden with the --block-size=size option.

It is possible that the details of this option change before the next stable XZ Utils release. This may include the meaning of the special value 0.

Parallel enabled by default or via switch. Also, no need to add sh as a dep.

If anybody is interested... This brings parallel compression!
