Not surprising given its VMS heritage.  I remember running shell
scripts under VMS on a VAX-11/780 that took hours to do what would
have taken minutes on an LSI-11 running Unix.  The whole Unix "small
tools working together" paradigm is based on the assumption that
process creation and death are fast and cheap.
