[buug] tee command hanging

Nick> ndunphy at bandon% mskstart cdsp 2>&1 | tee nick

Nick> # Done
Nick> <hanging here>
Nick> ^Cndunphy at bandon%

Are you so sure tee is to blame here?  What happens in these cases:

1/ mskstart cdsp >nick 2>&1

2/ script nick ; mskstart cdsp

3/ run under a real shell (bash/ash/ksh)

btw, do we know you?
