Oh gee that's a good idea.  And that just applies to the RPC call, right?  So it wouldn't interfere with broadcasting the transaction if/when the block is mined..??

Assuming that's the case, that's exactly what I'm looking for, thanks!  One quick question, is that code you highlighted also responsible for using sendrawtransaction via the bitcoin-cli program, or do I need to find and commend out code somewhere else for doing it via the cli?  Either way, it's no trouble to use the RPC interface, so you've definitely given me a working solution.  Thanks!
