Instead of using
limit=0to mean "unlimited", can we please useINT_MAX? It will simplify the code here:We can add a constant for it if it helps comprehension.
Aside from simplifying code I much prefer it when
0isn't used for "infinite" or "max", because as we--limitthe stack length with get smaller and smaller until we hit0, and then magically it gets bigger again?INT_MAXis a much better fit, IMO.There was a problem hiding this comment.

@morrisonlevi thanks for comments on this. I'll consider it if I start with this implementation as a separate PECL extension.
