EventConfig::setMaxDispatchInterval — Prevents priority inversion
$max_interval
   , 
    
    int $max_callbacks
   , 
    
    int $min_priority
   ): voidPrevents priority inversion by limiting how many low-priority event callbacks can be invoked before checking for more high-priority events.
Nota:
Available since
libevent 2.1.0-alpha.
max_interval
    
      An interval after which Libevent should stop running callbacks and check
      for more events, or
      0,
      if there should be no such interval.
     
max_callbacks
    
      A number of callbacks after which Libevent should stop running callbacks
      and check for more events, or
      -1,
      if there should be no such limit.
     
min_priority
    
      A priority below which
      max_interval
      and
      max_callbacks
      should not be enforced. If this is set to
      0,
      they are enforced for events of every priority; if it's set to
      1,
      they're enforced for events of priority
      1
      and above, and so on.
