See the write up on _BPX_SHAREAS in BPX1SPN and how _BPX_SHAREAS=YES/MUST
affects local spawn with the sticky bit is set.

It mainly affects where the loader starts looking for the program to be loaded,
namely LPA. Its a performance thing in the first place. Then, for some reason
unknown to me, IBM had to decide that such
on z/OS the sticky bit on an executable file affects how a spawn() and
_BPX_SHAREAS works.
Its kind of a hack (mess).

To me this is not a solution rather a circumvention to the real problem. No
process should recognize the difference in calling, i.e. fork()/exec() or
spawn(), a UNIX binary having or not having the sticky bit set.

Sure it will, at least as long as the file /bin/sh is the real shell binary,
aka load module. It's a performance penalty, only, since the shel
1755, the shell has the sticky bit set by IBM's installation default.
