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:

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

suggested by Sebastian Meyer in PR#17386.
* Interrupts can be suspended while evaluating an expression using
suspendInterrupts. Subexpression can be evaluated with
interrupts enabled using allowInterrupts. These functions can be
used to make sure cleanup handlers cannot be interrupted.
* R 3.5.0 includes a framework that allows packages to provide
alternate representations of basic R objects (ALTREP). The
framework is still experimental and may undergo changes in future...
