shell error

[utzoo!decvax!ucbvax!menlo70!sri-unix!allegra!psuvax!bear at Berkeley]

We are having a unusual problem with shell (sh). If a daemon (like UUXQT)
starts a program which executes

	execl("/bin/sh", "sh", "-c", "who one two three four five six", 0);

two shells

	sh -c who one two three four five six
	sh -c who one two three four five six

will appear. the second goes cpu bound and must be killed.  if instead

	execl("/bin/sh", "sh", "-c", "who one two", 0);

is executed or csh is used. the result is as exepected. the command 'who'
is not importain. anyone have any ideas what is happening?
