Well, Haskell does not really specify which mechanism to use. Most
implementations use call-by-need (a variation of the old call-by-name).
But any mechanism that is faithful to the semantics would, in principle,
be all right. So call-by-name is all right. As is spawning a thread
for the parameter (I don't know the name of this mechanism), as in pH.
