 I got the system installed on my notebook and now does not have any
 jail set up. 
 Tried to move io.d out:
 root at notebook ~src (git)-[53624fa...] #
 mv /usr/lib/dtrace/io.d /usr/lib/dtrace/io.d.bu
 root at notebook ~src (git)-[53624fa...] # dtrace -n 'syscall:::entry
 { @num[execname] = count(); }' dtrace: invalid probe specifier
 syscall:::entry { @num[execname] = count(); }:
 "/usr/lib/dtrace/psinfo.d", line 90: failed to resolve type
 kernel`struct thread * for identifier curthread: Module is no longer
 loaded 1 
 root at notebook ~src (git)-[53624fa...] #
 Serching through internet I found this:
 Maybe something not backported from CURRENT.
