Has anyone seen 'su username' hangs (the su process just stuck in
running-state) in ksh under SunOS 4.0.x (at least on Sparc so far) ??

A way out is to do a ctrl-c to get out of su.  And if you want to try 'su
usrname' later, you must logout entirely first, log back in and then you
can do 'su username' again.

I've never seen this under tcsh or csh though -- could it be some strange
interactions between ksh and su (or just su with init()) ??

Any pointers appreciated.
