[boost] more than 128 pthread_key_create

Hi,

we're using in our software extensive use of parsers based on spirits parsers. 
These parsers are declared as global objects, so we use them in a thread-safe 
manner by declaring BOOST_SPIRIT_THREADSAFE and PHOENIX_THREADSAFE. Works 
perfect on Linux. 
But not on Mac (OS 10.the.latest)) :(  The program doesn't even start. In the 
function

tss::tss(void (*cleanup)(void*))
{
    int res = 0;
    res = pthread_key_create(&m_key, cleanup);
    if (res != 0)
        throw thread_resource_error();
}

the pthread_key_create segfaults after the 128th constructor (thread limits on 
Mac). Note: at program start! There's only one thread running... We don't 
have more than 128 parsers (or maybe we do without knowing ;) 

This limit of 128 won't be changed by Mac in the next time (years?), so we 
have to find a way to avoid the construction of that amount of pthread_keys.

But how?

I would thank for any hint,
Jorge :)
