make running on.exit expr uninterruptible
Hi,
Is there currently any way to guarantee that on.exit does not fail to execute the recorded expression because of a user interrupt arriving during function exit? Consider:
f <- function() {
suspendInterrupts({
on.exit(suspendInterrupts(cntr_on.exit <<- cntr_on.exit + 1L))
cntr_f <<- cntr_f + 1L
})
TRUE
}
It is possible to interrupt this function such that cntr_f is incremented while cntr_on.exit is not (you might need to adjust timeout_upper to trigger the error on your machine...
