DESCRIPTION
API
debug heartbeat ?delta?
This method activates or disables a heartbeat with which to mon-
itor the event loop of an event-based Tcl application.
It reserves the debug tag heartbeat for its operation and writes
a message every delta milliseconds.
A delta-value <= 0 disables the heartbeat.
The message produced by the heartbeat contains a sequence
counter and the time in milliseconds since the last beat, thus
providing insight into timing variationsn and deviations from
the nominal delta.
