docs: Disables the current strand for scheduling purposes, until
  the specified deadline, unless the permit is available.
  <p>
  <p>
  If the permit is available then it is consumed and the call
  returns immediately; otherwise the current strand becomes disabled
  for scheduling purposes and lies dormant until one of four
  things happens:
  <p>
  <ul>
  <li>Some other strand invokes {@link #unpark unpark} with the
  current strand as the target; or
  <p>
  <li>Some other strand interrupts the
  current strand; or
  <p>
  <li>The specified deadline passes; or
  <p>
  <li>The call spuriously (that is, for no reason) returns.
  </ul>
  <p>
  <p>
  This method does <em>not</em> report which of these caused the
  method to return. Callers should re-check the conditions which caused
  the strand to park in the first place. Callers may also determine,
  for example, the interrupt status of the strand, or the current time
  upon return.
