A basic question:  which Scheme operations (e.g. variable lookup or
mutation, function calls) are atomic w.r.t. context switches (i.e. run
from start to end before the next thread takes over).  Or, should we
always lock shared variables during access?  (I'm thinking of value
delivery without synchronisation:  one thread that may set a variable and
another one that looks occasionally for the result.)
