The current code tries to use the same field in the interrupt handler as
both a "next" pointer for a singly-linked list and as an in-use flag.
This obviously does not work all that well. This change adds a separate
ih_busy flag to mark the handler as in-use, leaving ih_pending for use by
the list code.
Testing by *many* (thanks).
