He says:
Ok the extra INTOFF is the one in exverror().
In almost all cases this doesn't matter because the longjmp()s
all end up in main() and the FORCEINTON call sorts it out
for the next command.
(There are a significant number of INTON/OFF mismatches through
the error paths...)
In any case the above failure can be 'fixed' by changing 2 (I think
they are both needed) INTON calls to FORCEINTON within evalcommand.
The following patch seems to work:
We should really look in the code and fix the INTON->INTOFF pairs.
- The MD netbsd32_machdep.h header now defines the 32-bit pointer type
instead of using u_int32_t everywhere,
- The MD netbsd32_machdep.h header now defines a macro (at least on
current implementations) which converts a 32-bit pointer to its 64-bit
equivalent,
- Change the MI code to utilise the above two items in all the right places,
- Implement netbsd32___sigaction_sigtramp().

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
