first is a timeout value in seconds, and the second is a memory limit
in megabytes. Either one can be @scheme[#f] for disabling the
corresponding limit; alternately, the parameter can be set to
@scheme[#f] to disable all limits (in case more are available in
future versions). The default is @scheme[(list 30 20)].
@scheme[#f] to disable all limits (useful in case more limit kinds are
available in future versions). The default is @scheme[(list 30 20)].
Note that these limits apply to the creation of the sandbox
environment too --- even @scheme[(make-evaluator 'scheme/base)] can
fail if the limits are strict enough. Therefore, to avoid surprises
you need to catch errors that happen when the sandbox is created.
so, for example, if the memory that is required to
create the sandbox is higher than the limit, then
@scheme[make-evaluator] will fail with a memory limit exception.
When limits are set, @scheme[call-with-limits] (see below) is wrapped
around each use of the evaluator, so consuming too much time or memory
results in an exception. Change the limits of a running evaluator
