I managed to reproduce the segfault you are seeing in slapd, which is
caused by a problem in libthr.so, introduced in r234947.

Please apply the attached diff, rebuild lib/libthr and install it, and
then try your slapd tests again.  Let us know. :)

@David, can you please review this diff?  It looks like there was a
mistake merging from Perforce, where you also moved the line:

                sc = SC_LOOKUP(wchan);

to the top of the _sleepq_add() function, just before the call to
_sleepq_lookup().  If this isn't done, sc may be uninitialized when it
is dereferenced later on in the function.
