Correct. It is admittedly very Unixish at the moment.

Effectively, yes. There is also a symbol RTLD_LOCAL, which is 0 on
most systems, and it may be reasonable to add RTLD_LAZY (defer
resolution of function symbols until they are called the first time).

Anyway, my main point is that this should be a run-time option. If the
APIs can merge, that might be a good thing (even if it means to
deprecate setdlopenflags); if that is not feasible, I'd atleast
recommend that you put the control over extension loading also into
sys.
