--- Comment #23 from Phil Shafer <phil@freebsd.org> ---
Another interesting data point, not that I'm sure what it means:

    % env LD_PRELOAD=3D/usr/lib/libpthread.so /tmp/uptime
     5:26PM  up 4 days,  9:22, 3 users, load averages: 0.55, 0.52, 0.51

(where /tmp/uptime is a symlink to /usr/obj/.../w/w).
(see

zilla_show-
5Fbug.cgi-3Fid-3D227552&d=3DDwICAg&c=3DHAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDT=

Does the mean that the use of __thread requires -lpthread?  My
understanding was that the startup code handled thread-specific
data for the main thread of execution.

Thanks,
 Phil
