===================

i guess this demonstrates what you mean by "asynchronous":
 	{ echo -n a ; echo -n b >&2 ; echo c ; echo d >&2 ; }

(on freeBSD, "echo -n" suppresses the newline. i don't think that option 
is portable across all flavors of *nix)

the results are ~not~ what i would've though  ;)

it also doesn't do well at all with this command:
 	gpg < clearsigned_file
which outputs some lines as STDERR, other lines as STDOUT.

and this isn't working anything the way i'd expect it to:
 	time date > file_stdout 2> file_stderr

it seems that i can't redirect STDERR unless i run the command in 
curly-braces or parenthesis...
 	{ time date ; } > file_stdout 2> file_stderr

back-quotes don't even work.
