By all means:  given the frequency and variations I'm testing
theses days.

Furthermore: even a wrapper could created minor differences in
the actual execution sequence.  Read: timing.
To have or not to have it might be critical for the bug you are
after to escape for some more time.

Folklore along the way: once we ran into a gcc bug.  It did show
up rarely (but eventually too often) in RScheme's block allocation.
(Turned out to be only at the then new AMD 64 due to bad instruction
scheduling of gcc.  The C code was valid.)
