GPIO level changes shorter than the sample rate may be missed.
The daemon software which generates the callbacks is triggered
1000 times per second. The callbacks will be called once per
level change since the last time they were called.
i.e. The callbacks will get all level changes but there will
be a latency.
If you want to track the level of more than one GPIO do so by
maintaining the state in the callback. Do not use [*gpio_read*].
Remember the event that triggered the callback may have
happened several milliseconds before and the GPIO may have
changed level many times since then.
