new systems using geom mirror hanging

[Randy Bush]

<gossip, not hard fact>

i hope to follow up with more useful info.  but a number of 8-current
systems cvsupped in the last few days are hanging.  only those using
geom mirror.

here is a bit of strange log from one

Apr  5 00:13:54 work0 kernel: swap_pager_getswapspace(16): failed
Apr  5 00:16:48 work0 kernel: swap_pager_getswapspace(16): failed

Apr  5 00:16:48 work0 kernel: swap_pager_getswapspace(16): failed
Apr  5 00:16:48 work0 kernel: swap_pager_getswapspace(3): failed

and another

Apr  5 00:08:24 rip kernel: swap_pager: out of swap space
Apr  5 00:08:25 rip kernel: swap_pager_getswapspace(2): failed
Apr  5 00:08:25 rip kernel: pid 46478 (named), uid 53, was killed: out of swap space


these are 4GB systems
