The use of fluids in your code (MAKE-FLUID, FLUID-REF, WITH-FLUIDS) is
perfectly fine.  

There has been discussion in the mailing list regarding FLUID-LET,
which (despite its name) has nothing to do with fluids (and which you
didn't use).  FLUID-LET tries to simulate dynamic scoping using
DYNAMIC-WIND and SET!, which fails in a multi-threaded environment.
