Hi Mike#1,
I noticed that on japsand that are currently 5 instances of qemu-system-arm running, and 4 of them are maxing out 1 CPU core each.
Did you start doing ARM builds? Creating ARM builds is on my long-term todo list.
(Especially raspbian builds, which is Debian armhf for ARMv6. Normally, Debian armhf is for ARMv7.)
