Yeah, the preload would have to be part of the server configuration,
requiring appropriate care in choosing the preloaded modules (they'd
normally be stdlib modules which rarely do uncivilized things like
launch new threads on import).  It wouldn't do to let random user
scripts into the preload.

One could imagine languages in which this could be enforced by a
static type system.  Hmm.
