[Rd] R as shared library

[Warnes, Gregory R]

Jeff,

Does apache use threads?  If it does, I would recommend *not* directly
putting R into the apache server for the simple reason that R is not
thread-safe.

You might find it simpler (and cleaner) to use the RSOAP
(http://rsoap.sf.net) interface to connect R with apache.  I originally
created RSOAP to get allow me to connect the ZOPE web application system's
web server to R.

-Greg
