not all jobs complete if not resumed

[chenhu66]

Hi subhranil,

i tried several on github, yours is sofar the best. But still an issue:
if not resumed, only a couple of jobs are done, not all;
if resumed, i got a warning: [THREADPOOL:RESM:WARNING] Pool is not suspended!
Following my main.c for reference:

void longJob(void *dummy){
volatile unsigned long long i;
// for (i = 0; i < 1000000000ULL; ++i);
printf("job done\n");
}

int main(){
uint64_t size=11;
ThreadPool *pool = createPool(size);

size=20;
for(int i = 0;i < size;i++)
	addJobToPool(pool, &longJob, NULL);

resumePool(pool);

waitToComplete(pool);
printf("all jobs completed\n");
destroyPool(pool);
printf("pool destroyed\n");

}
