=46rom xz(1):

       To  prevent uncomfortable surprises caused by huge memory usage, xz =
has
       a built-in memory usage limiter. While some operating  systems  prov=
ide
       ways  to  limit  the  memory  usage  of processes, relying on it was=
n't
       deemed to be flexible enough. The default limit depends  on  the  to=
tal
       amount of physical RAM:

[...]

The default limit can be overridden with --memory=3Dlimit.

and

ENVIRONMENT
       XZ_OPT A space-separated list of options is parsed from  XZ_OPT  bef=
ore
              parsing  the  options  given on the command line. Note that o=
nly
              options are parsed from XZ_OPT;  all  non-options  are  silen=
tly
              ignored.  Parsing is done with getopt_long(3) which is used a=
lso
              for the command line arguments.
