I've been a c-ares maintainer for twenty years and it has been (optionally) 
used in curl for just as long. I don't understand what you're saying, but 
c-ares is not using any extra threads (the way curl uses it) but is instead 
entirely non-blocking and used in the same thread.

I'm not aware of any current bugs in that area, but there's always a risk 
there's someting else. If you can reproduce with something smaller than a full 
PHP then submit an issue and we can work on it!
