It could also (potentially!) have to do with module unloading. If module Hilbert
overwrites a previously released module block, which is however still referenced
by other loaded modules or data structures (e.g., via type references or procedure
variable references), the entire system may become unstable at that moment
(recall that FPGA Oberon is inherently unsafe with respect to module unloading).
