1 million of district symbols limit #80

To reproduce

Review point M6 in #66 (comment) is very valid

M6 — At the 1M cap, the error message's remedy is not performable through SenderPool (out-of-diff). getOrAddSymbol says "close this sender and build a new one", but PooledSender.close() (:153) gives the delegate back rather than closing it, and reset() does not clear globalSymbolDictionary. A delegate that hit the cap is handed to the next borrower still full, throwing on every new symbol value. Only incidental reapIdle recovers it.
