The primary question for me is whether nesting should be allowed or not.
That would mean a reference count behind the flag.
This `reference count' gets stored on the stack. The caller does:
int bound = curlwp_bind();
... psref_wotsit ...
curlwp_unbind(bound);
If it was already bound, bound = 1 and curlwp_unbind does nothing; if
it was not already bound, bound = 0 and curlwp_unbind unbinds it.
Perhaps the name should be `curlwp_bound_restore' or something else to
emphasize this, but I haven't come up with one that I like better on
aesthetic grounds.
