Doug's statement was a bit too absolute.  The default threading package
is libc_r, which is purely a userland threading package and does not
allow threads to be scheduled on concurrent CPUs.  libkse does allow
this, and can be enabled be either linking directly to it, or using the
libmap.conf(5) facility.
