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=

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.
