Yes, I keep coming back to this worry in various contexts.  If Guile
is set up to act as a multithreaded, multiuser server, lots of things
that are currently global need to be fluids.

It might be cool to think up a cunning way of achieving this
transparently - i.e. without requiring modules to explicitly make
their internal state variables fluids.
