// History:
// Any longer than 1s is an unreasonable length of time to delay booting.
// If you're hitting this timeout, check that you didn't make your
// sepolicy regular expressions too expensive (http://b/19899875).
// Update:
// It is bad to allow device to randomly fail to boot. So, we should
// instead log an error and abandon boot process if we have waited
// for a *considerably* long period of time. For attempts that do not
// exceed the treshold, we keep a record of how long it took for further
// optimization work.
// Also, a longer wait period before timeout gives slower builds like
// heavily instrumented debug builds (e.g. KASan) a chance to fully boot.
