Comment (by Ainsley Pereira <boostbug_at_[hidden]>):

 I did some profiling on the wave preprocessor in tools, and discovered
 that over 71% of its time was spent getting thread specific storage for
 code in spirit/phoenix/closures.hpp. (Another 4% was spent setting tss
 data.) It seems to be possible to define BOOST_WAVE_THREADING_SUPPORT to
 0, but my bjam skills failed me and I was unable to build/link it with
 that to retest. I hope the information is useful to someone who knows more
 about the spirit closures stuff.
