Bash hashes commands and paths so there may be so code to rescan previously
unavailable paths.  Try "hash -r" after setting your path.

Also, about a year ago, I ran into a similar problem.  It seems that if you
used commands to put together a PATH, sometimes it would get into a state
where the command prompt took about a second to return.  If you scan the
archives for "slowing down" and my name, you can get the details.  I was
under the impression that this problem is fixed long ago but I never had a
reliable test and I haven't seen it since.

When the slowness happens, I set my path to just /usr/bin as a test... and
the problem's still there.

Unfortunately, I confused the issue by running cygcheck during a NORMAL
session.

So you guys are right - I need to fix that in my path - but that's not the
main problem.

I've been waiting for it to recur (happens for a day every week or so) so
I can strace ls and see where the time's being spent.
