Pete,
as already pointed out by Peter, the leak seems to be caused by the 
pthread library, not boost. Most likely it isn't harmful. It looks 
independent of the number of threads created. I guess it is related to 
thread local storage management.

You might try the below code snippet, which gives me the same valgrind 
report than the example using Boost.Thread:

#include <pthread.h>

void* fn(void* p)
{
     return NULL;
}

int main()
{
     pthread_t th;
     pthread_create(&th, NULL, fn, NULL);
     pthread_join(th, NULL);
     return 0;
}

Roland
