I'm using nsvhr/nsunix without any problems. Dossy adapted Jerry's work for AOLserver 3.5 and is available for download from the aolserver CVS. The tags are nsvhr and nsunix.
I've also tried Pound (http://www.apsis.ch/pound/) but that proved to be incompatible with a series of ns_writes as used in ACS bootstrap. Pound closes the pipe immediately after the HTTP headers are returned and subsequent never make it too the client.
The nsvhr/nsunix combination is fairly light weight and you don't lose any logs.
