-current host, 10.1 client loops

[Poul-Henning Kamp]

I'm seing bhyve go into some kind of endless loop while trying to
compile the gcc port on 10.1 as guest.

In one case CTRL-T on the console kept working, but showed an rm(1)
process raking up CPU time.

Are there known bogon in current/bhyve or using 10.1-R/i386 as a guest
I have not spotted ?

How does one debug stuff like this ?

Bhyve started with:

        sh /usr/share/examples/bhyve/vmrun.sh \
                -m 1G \
                -t ${VMN} \
                -d ${P}.root.dd \
                -d ${P}.swap.dd \
                -d ${P}.tami_install.dd \
                -d ${P}.tami_git.dd \
                vm${VMU} || true
