I don't do embedded work, but I see that no-one has answered your
question, so I'll have a stab at it.  My best guess would be:

1) do frequent, explicit gc calls. It will increase your overhead but
may lead to more predictable behaviour, and presumably that's
important in your embedded app. You may also be able to evict some of
your objects out of the heap, and avoid gc altogether.  See
object-evict in the documentation for the "lolevel" module, but be
sure to read the warnings too. Of course you can also write some parts
of your app in C and use the FFI to control it.

2) Run separate processes.

(If I am wrong-ish, then hopefully my wrongishness will inspire a
righter soul to correct me. :-)
