Hard closing without shutdown is necessary, but we continued to poll
and read on an fd that would be re-used to open eg. a ZIP file:
[ kitbgsv_007_001 ] TRC #19: Incoming WebSocket data of 13522 bytes: 50 4B 03 04 14 00 00 08 00 00 29 9C 90 58 33 26 AC A8 2F 00 00 00 2F 00 00 00 08 00 00 00 6D 69 | PK........)..X3&../.../.......m"
...
[ kitbgsv_007_001 ] ERR #19: An unfragmented message or the first fragment of a fragmented message must have the opcode different than 0| net/WebSocketHandler.hpp:452
which would then close the file unhelpfully.
Not removing the socketHandler when cleaning up means that
we trigger the ForKit's ServerWSHandler::onDisconnect which
SigUtil::setTerminationFlag() causing all 2nd kit processes
to expire on start.
We also want to ensure that we update the thread-id of the last
forkit process before we start removing sockets and checking
thread-ids.
We want to get rid of the parent process' sockets we inherited
but don't need very cleanly post fork.
