This doesn't work correctly, since the span is dropped when the function returns, calling `try_close` on that span. We could remove the inner value in this case, but then `try_close` will _never_ be called on that ID, leaking the parent. If the span is dropped *after* the new span is created, instead, everything will work correctly, because the subscriber will have already increased its reference count (as it now has a child). Thus, only `&Span` is valid here. Signed-off-by: Eliza Weisman <eliza@buoyant.io>

This doesn't work correctly, since the span is dropped when the function

try_closewill never be called on thatID, leaking the parent. If the span is dropped after the new span is
created, instead, everything will work correctly, because the subscriber
will have already increased its reference count (as it now has a
child). Thus, only
&Spanis valid here.Fixes #688
