<h3>Checking Periodic Scan Rates</h3>
<p>Code has been added to the IOC startup to better protect it against bad
periodic scan rates, including against locales where <q><tt>.</tt></q> is not
accepted as a decimal separator character. If the scan period in a menuScan
choice string cannot be parsed, the associated periodic scan thread will no

time. The <tt>scanppl</tt> command will also flag the faulty menuScan value.</p>
