please try a simple test compress 50 MB with XZ and GZ, LZO, LZ4
or BZIP2 - XZ is *magnitudes* slower in any case, there is simply
nothing to optimize - XZ

Also, I am not sure that ENOSPC is appropriate here (and everywhere) ?
Why not ENOMEM (since

Looks good otheriwse.

No, I haven't. But I seriously doubt how it could improve things enough to
make a difference ( 2 orders).
I generated some coredumps, fixed some messages, and things seem to
Add liblz4 as an optional dependency when requested with --enable-lz4, and
use it in preference to liblzma for journal blob and coredump compression. To
retain backwards compatibility, XZ is used to decompress old blobs.
Things will function correctly only with lz4-119.
Based on the benchmarks
