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.

15Description:
16		The limit that 'schedule_delay' (see below) will be
17		increased to. The default value is 32 seconds.

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).
