Would it make more sense to implement this as part of an rlimit subsystem,
which also supports limiting e.g. address space, CPU time, number of open
files, etc.? If we create one subsystem per resource, I'm afraid we're
going to see quite some time spent in all those loops, and the options for
cgroupfs is going to become pretty long if you want to exclude just one or
two of the subsystems for one particular mount point.
