f.y.i. - On our 6.0 system JSMAIN is at B152 for active sessions and jobs
(CI is son process).

Following is an extract from :SHOWPROC 1;SYSTEM;TREE  (pin 56 - S147)

B100* 0:02.974  WAIT             50   (SESSION.PUB.SYS)
B152  0:00.489  WAIT   S116        52   (JSMAIN.PUB.SYS)
C152  0:03.826  WAIT   S116          55   :SJ
B152  0:00.503  WAIT   S147        77   (JSMAIN.PUB.SYS)
C155  0:00.737  READY  S147          56   :SHOWPROC 1;system;tree
C152  0:00.146  WAIT   S147          72   (VTSERVER.NET.SYS)
