>Description:
	BIND9 dig never terminates.  the binary is compiled with
	unproven-pthreads 0.17. (pkgsrc/devel/unproven-pthreads)

	the last part of ktrace output look like follows.
	there seem to be something wrong in thread management code of
	unproven-pthreads 0.17, or there is some bad interaction between BIND9
	dig and unproven-pthreads.

>How-To-Repeat:
	- install pkgsrc/net/bind9.
	- try "/usr/pkg/bin/dig bsdports.org. any".
	- the program never terminates.
>Fix:
	not sure, i'm a single-threaded guy...
