Some versions of sh have <>, but it's not always documented.
The v7 and v9 shells parse <> and set a flag (IORDW), but
the flag is never honoured.

I suppose one could write a simple prefix command, taking a file name,
descriptor number, and command to run:

	rdwr /mnt/webcookies/http 4 'echo http://www.foo.baz >[1=4]; cat <[0=4]'
