As far as I know the state letters come from the third field in the
/proc/<pid>/stat file. A more verbose version of this field appears in the
/proc/<pid>/status file (look for 'State:'). According to task_state_array[]
(fs/proc/array.c in the kernel sources) 't' translates into "tracing stop",
while 'T' is just "stopped".
