System: NetBSD nbair.virtual.network 6.99.17 NetBSD 6.99.17 (GENERIC) #13: Sat Mar 16 11:23:16 JST 2013 jmmv@nbair.virtual.network:/home/jmmv/os/netbsd/amd64/obj/home/jmmv/os/netbsd/src/sys/arch/amd64/compile/GENERIC amd64
Architecture: x86_64
Machine: amd64
>Description:
	The entropy_polled_sensor and entropy_interrupt_sensor tests in
	dev/sysmon/t_swsensor are flaky: they fail in various steps,
	sometimes.

	I've seen failures in 15a and 15b for sure, and I seem to recall
	failures in 14* as well.

	This is on amd64 and not inside qemu.
>How-To-Repeat:
	Run t_swsensor in a loop and wait for it to fail.  Usually will fail
	on the first try.
>Fix:
	Dunno.  Fix the tests or fix the code.
