[MLton-user] Destructive update

[Henry Cejtin]

ram-slop is used to calculate the max amount of RAM that the MLton process
should use, so it really corresponds to adjusting max-heap.
The point is that if you want to be able to run more than one MLton process
at the same time, then it is the maximum any MLton process will use that you
want to adjust.  There is no reason for it to use that size unless it `needs'
it.
I always think of fixed-heap as being a much more weird option.
