|

|
* incrementing the smallest attribute until an unused value is found.
|
|
*
|
|
* NOTE: Both mechanisms do NOT prevent race conditions or toe-stomping, so
|
|
* care must be taken when actually creating the entry to check that the number
|
|
* returned here has not been used in the mean time. Note that the two different
|
|
* mechanisms may (will!) return different values as they use different algorithms
|
|
* to arrive at their result. Do not be alarmed if (when!) this is the case.
