Okay why not it's a reasonnable optimization. But I'm a bit surprized, a mutex lock/unlock should be on i386 architecture not much more expensive than an atomic test and set operation. If it really show up int the profile maybe the thread library aren't really optimal. > Beside smoother creation of local variables, this would also > speed up the implementation of EXSLT: Result Tree Fragments > are created in the split() and tokenize() functions.
