commit 323617f649c0966ad5e741e47e27e06d3a680d8f upstream.
The thread that calls the module initialisation code when a module is loaded is not guaranteed [in fact, it is unlikely] to be the same one that calls the module cleanup code on module unload, therefore, `Module` implementations must be `Send` to account for them moving from one thread to another implicitly.
