No. Signals can be sent to any process by any process with the same
or higher privileges in the system. This is a fundamental unix truth.

I don't think the foreign function interface is neccessarily
involved, but some other part of Haskell can of course be sending a
signal to your process.
Write a minimal example and run it with strace -fF and hope that you
will see some process sending it.
