Performance lag?

Hi,

(for the linux environment)

In the function _duma_allocate(), during the loop where we try to find the free slot, even after finding the free slot and 2 empty slots, we run through all the slot structures. If I am correct, by design, the empty slots come after the free slot, so after we find the 2 empty slots, shouldn't we break the loop?

```
} else
#endif
if (DUMAST_EMPTY == slot->state) {
if (!emptySlots[0])
emptySlots[0] = slot;
else if (!emptySlots[1])
emptySlots[1] = slot;
**else
break;**

```
For example,
test program tstheap with a test duration of 10000 runs for 160 seconds without breaking the for loop, and runs 120 seconds with breaking the loop.
