Waiting vs Not Waiting

The $transactionCount obtained by calling getTransactionCount() is only accurate if ALL the previously submitted transactions have been mined. There's some code that waits for the transaction to be mined. If the wait is removed or bypassed then it will be necessary to manually count how many transactions were submitted and manually increment $transactionCount.

Search for information on the ethereum nonce to better understand the importance of the transaction count.
