I ran the threaded tests Eric supplied using helgrind to check for data 
races, and got several reports of problems in the std::string stuff.  Of 
course, helgrind does have a tendency to report false positives, so I 
thought I'd check if I still got the reports when using a different STL 
implementation.

Unfortunately, I havn't yet been able to get Xapian compiled using 
STLport - I'm giving it another go this morning.
