+// possible that the error handler itself may crash or die on an internal
+// error, for example, when the stack/heap is badly damaged. We must be
+// able to handle recursive errors that happen inside error handler.
+//
+// Error reporting is done in several steps. If a crash or internal error
+// occurred when reporting an error, the nested signal/exception handler
+// can skip steps that are already (or partially) done. Error reporting will
+// continue from the next step. This allows us to retrieve and print
+// information that may be unsafe to get after a fatal error. If it happens,
+// you may find nested report_and_die() frames when you look at the stack
+// in a debugger.
+//
+// In general, a hang in error handler is much worse than a crash or internal
+// error, as it's harder to recover from a hang. Deadlock can happen if we
+// 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
+// error handler and all the functions it called should avoid grabbing any
+// lock. An important thing to notice is that memory allocation needs a lock.
+//
+// We should avoid using large stack allocated buffers. Many errors happen
+// when stack space is already low. Making things even worse is that there
+// could be nested report_and_die() calls on stack (see above). Only one
+// thread can report error, so large buffers are statically allocated in data
