At the first sight, it may look as if you were saving a fork(), but the 
opposite is true. Try the following:

OPSYS= ${:!${UNAME} -s; echo . 1>&2!:S/-//g:S/\///g}

which prints a dot whenever it is called. When I run "bmake show-var 
VARNAME=OPSYS" in the pkglint directory, the command is called 66 times.
