Trying to get clipboard into paste buffer

I'm using the following bind to get the x clipboard into the paste
buffer and then paste it:

bind P eval 'exec sh -c "xsel -n -o -b > /tmp/screen-exchange"' 'readbuf' 'paste .'

There seems to be some kind of timing problem, because readbuf seems
to execute before xsel has pasted and pastes the old contents of
screen-exchange. If I execute it twice, it works as it should.

If I just have the xsel command it does copy into screen-exchange so
I know that that's working, and I can then run 'c-a < c-a ]' and it
works that way too.

I tried adding a sleep command in there but it didn't make any
difference.

Any ideas on how to get this working?
