Thread-safe SQL web password auth

We're running the Netscape Enterprise 2.01 web server and the Informix 7.1 SQL server on a Solaris 2.5.1 box. We're trying to get the web server setup so that it authenticates user passwords and path access from our Informix database rather than the ACL files. I've got this working fine on a test server, but when I turned it on for our heavily-used primary server, I found that SQL calls into Informix (via ESQL/C) are not thread safe. Whenever two SQL queries from separate threads of the same web server process get run at the same time, the latter call gets error -439, indicating that the server connection is busy. Is it possible to run a different database connection for each thread? How? If not, what's the best way to lock then connection whenever I'm executing a query? I can't find any mention of multi-thread support anywhere in the Informix manuals. Does anyone have any idea how I can get around this without eating up gobs of CPU time on each and every HTTP query?
