arch_int_restore_interrupts

I didn't open a ticket because I can't really call it a bug since there is
this ToDo in the dprintf function

    // ToDo: maybe add a non-interrupt buffer and path that only
    //  needs to acquire a semaphore instead of needing to disable
    //  interrupts?

Basically I'm doing an heavy use of TRACE calls (a.k.a. dprintf) to debug
my thread, and sometimes (actually often) my systems hangs. At first I
thought
I introduced a deadlock but then, by looking at the stack frame
in kdl I saw that the system was blocked at

arch_int_restore_interrupts
restore_interrupts
dprintf
mythread
etc...

so I'm wondering if this ToDo is going to become history any time soon. :)
