The impatient should use a tracing utility instead of encrufting
individual utilities.

Tracing utilities coulld be extended to report kernel info. E.g.,
the current [blocked] syscall can be found and reported in the same
way and detail that ddb does for backtrace and ps. Names would be
harder to find, but a full backtrace normally locates what is blocking.
