Your application would have to be *very* efficient (much more efficient than, say, Croquet's scene-graph):

[1000000 timesRepeat: [gl glGetError]] timeToRun  627
[1000000 timesRepeat: [Object new; new; new; new]] timeToRun  747
[1000000 timesRepeat: [OrderedCollection new add: 1]] timeToRun  1078

We're talking less than a microsecond per FFI call.  Your whole application would have to be *heavily* optimized before this became the #1 bottleneck.
