36 * C shell - process structure declarations
40 * Structure for each process the shell knows about:
41 * allocated and filled by pcreate.
42 * flushed by pflush; freeing always happens at top level
43 * so the interrupt level has less to worry about.
44 * processes are related to "friends" when in a pipeline;
45 * p_friends links makes a circular list of such jobs
