>Description:
I experience a seemingly phantom load avg and very slow disk IO after running the test suite for ruby. I have verified that all ruby processes have gone away, but still the load is there and disk IO is slow. Have been unable to identify the source of the load or slow disk IO, but rebooting fixes it.
>How-To-Repeat:
sysctl kern.chroot_allow_open_directories=2
cd /usr/ports/lang/ruby19
make install
make validate
>Fix:
