5Description:
6 The maximum number of times the balloon driver will
7 attempt to increase the balloon before giving up. See
8 also 'retry_count' below.
9 A value of zero means retry forever and is the default one.

23Description:
24 The current number of times that the balloon driver
25 has attempted to increase the size of the balloon.
26 The default value is one. With max_retry_count being
27 zero (unlimited), this means that the driver will attempt
28 to retry with a 'schedule_delay' delay.

34Description:
35 The time (in seconds) to wait between attempts to
36 increase the balloon. Each time the balloon cannot be
37 increased, 'schedule_delay' is increased (until
38 'max_schedule_delay' is reached at which point it
39 will use the max value).
