/// The SSX kernel dump produces a formatted snapshot of the state of the
/// kernel and the mapped threads. This API does not manipulate the machine
/// context; If it is required to produce a precise snapshot then the caller
/// will need to make the call from a critical section.
///
/// The following information is standard in the dump
///
/// - The interrupt and thread state of the kernel
/// - The state of each thread
/// - A stack trace for each thread
///
/// Options : TBD
///
/// \bug There are likely several bugs in the current implementation due to
/// the assumption that the code is being called from a state in which the
/// kernel context is not changing. We don't have time to code and test the
/// most general implementation now.  To guarantee correct operation the API
/// must currently be called from an SSX_CRITICAL critical section.
