// In general, a hang in error handler is much worse than a crash or internal

|
|

// try to grab a lock that is already owned by current thread, or if the

// owner is blocked forever (e.g. in os::infinite_sleep()). If possible, the

233 |
// error handler and all the functions it called should avoid grabbing any

//
|
