>Description:
When trying to use a programme that has a lot of loaded symbols the time it 
takes to start up is unusually long.  For instance from pkgsrc misc/koffice 
krita would take 10 minutes to start up.

So I came across this thread:

http://mail-index.netbsd.org/tech-userlevel/2010/02/24/msg003325.html

And so I tried it with current 5.99.51 and krita would start up in 10 seconds.
>How-To-Repeat:
Install koffice and dependant packages on NetBSD 5.0 or 5.1

Start krita.  It will take approximately 10 minutes to start up

If you examine the process with gdb you will see that it takes a long time in 
rtld functions.
>Fix:
The solution was to backport ld.elf_so from current.

So I have the files at the following link although they are for the i386 only 
(my current platform).  It would be easy to add to other platforms just the 
addition of conditional compilation code for the lack of tls.h in NetBSD 5.0.

So here is the link:

I think it should be added or something similar to the NetBSD 5 branch as it 
affects the current stable release 5.1.

I hope this helps and was appropriate.

Regards,

Nat.
