Yup, I read through the module doc pages and the warnings there are quite 
explicit. I guess for specific use in a complex, threaded environment a 
homemade string-massaging routine like those offered by Skip et al would be 
safer. Fortunately (or not) in my case the context is extremely simple (as 
I can't even get a second thread to run, see separate posting :-), so 
"locale" does the job nicely.
