Shawn O. Pearce 68ab451d39 ProgressMonitor: Refactor to use background alarms Instead of polling the system clock on every update(1) method call, use a scheduled executor to toggle a volatile once per second until the task is done. Check the volatile on each update(int), looking to see if output should occur. This limits progress output to either once per 1% complete, or once per second. To save time during update calls the timer isn't reset during each 1% of output, which means we may see one unnecessary output trigger if at least 1% completed during the one second of the alarm time.

Shawn O. Pearce 68ab451d39 ProgressMonitor: Refactor to use background alarms

Instead of polling the system clock on every update(1) method call,
use a scheduled executor to toggle a volatile once per second until
the task is done.  Check the volatile on each update(int), looking
to see if output should occur.

This limits progress output to either once per 1% complete, or once
per second.  To save time during update calls the timer isn't reset
during each 1% of output, which means we may see one unnecessary
output trigger if at least 1% completed during the one second of the
alarm time.
