Change Details

Exiting processes that have been removed from allproc but are still executing are not yet marked PRS_ZOMBIE, so they were not listed (for example, if a thread panics during exit1()). Using the pidhash for all processes does display them in a different order, but works reliably.

Exiting processes that have been removed from allproc but are still executing are not yet marked PRS_ZOMBIE, so they were not listed (for example, if a thread panics during exit1()). To detect these processes, clear p_list.le_prev to NULL explicitly after removing a process from the allproc list and check for this sentinel rather than PRS_ZOMBIE when walking the pidhash. While here, simplify the pidhash walk to use a single outer loop.
