What
Before a background session starts, its name is checked against the names of existing jobs and, if it clashes, is given a suffix like (2). Repeat clashes read the existing number back out and increment it.
Details
The seed records that the name came from a collision rather than being chosen directly.
Renaming is best effort: if the list of existing jobs cannot be read, the original name is used as is.
