 No doubt about it.  Then if the number of entries was to be huge, then
lines output to the log buffer could be limited to 80 characters.  With
the use of sprintf() it would be rather trivial.  And you would avoid any
concerns about stack consumption.

 Please note that with MPS 1.1 systems the number of "unconnected" I/O 
APIC inputs can be considerable.
