MC problem in RH8.0 (Follow-on)

I could not reproduce it on Red Hat 8.0.  I tried to reproduce it on tmpfs
and reiserfs by creating long chains of directories.  My subshell is bash
2.05b from Red Hat.

What filesystem do you use?  What is the directory name?  I just don't
know how many levels you need (hundreds, thousands).  Please try running
mc without subshell support: "mc -u" - maybe it will work faster.  What
shell are you using?

Are you running nscd?  Try running or killing it and check if it makes any 
difference.  Are you using any centralized user database, like NIS?

I don't know.  To me it sounds more like a filesystem bug or a bug in the
subshell support (or may be in the subshell itself).

The latest versions of Valgrind (http://developer.kde.org/~sewardj/)  
include a profiler.  Maybe you could try using it to find where mc spends 
most of the time?
