The discussion of 220.127.116.11 Interrupt Handlers in the Scsh manual suggests
to me that when the scshvm receives e.g. a TSTP signal, it delivers the
corresponding interrupt to the running Scheme code that may choose to
block or handle it. Concretely, I would have thought that the script
below reads and prints a Scheme datum before it may yield to suspension.
-- It doesn't (as of scsh-0.6.2 / Linux kernel 2.4.10). So what's the
right way to protect code from catchable Unix signals?
-o low-interrupt -s
; the struct LOW-INTERRUPT serves the proc REMOVE-INTERRUPT
(remove-interrupt interrupt/tstp (enabled-interrupts))
