// This is a testing PKCS #11 module that simulates a token being inserted and
// removed from a slot every 50ms. This is achieved mainly in
// Test_C_WaitForSlotEvent. If the application that loaded this module calls
// C_WaitForSlotEvent, this module waits for 50ms and returns, having changed
// its internal state to report that the token has either been inserted or
// removed, as appropriate.
// This module also provides an alternate token that is always present for tests
// that don't want the cyclic behavior described above.
