The only issue is that __thread is a GCC specific extension, so I'm not
sure this will work for the Solaris folks ?
http://gcc.gnu.org/onlinedocs/gcc/Thread_002dLocal.html
The other option is to use the POSIX APIs pthread_getspecific &
pthread_setspecific. It'll make the code alot more cumbersome, but
would certainly be portable. I'm certainly willing to do this though
if need be...
