Should Primitive-like Utiltiy VIs be Reentrant?
[cross-post]
At OpenG, we've recently discussed the possibility of setting our small primitive-like utility VIs as subroutine. Now, we're discussing whether we should make these VIs reentrant. Ton Plomp asked;

I created major problems for LabVIEW when I made the "Trim Whitespace.vi" be reentrant a few versions ago. Just launching LabVIEW's Getting Started Window spawned 150+ copies of that subVI. It was a major memory hog. In LV8.5, that subVI is no longer reentrant. The tradeoffs between the thread synchronization and the memory usage were such that not being reentrant is better.
Now, in LV8.5 we also introduced pooled reentrancy. The LabVIEW R&D team has been seriously debating a recommendation
