testSlotWorkAndBudget

tcmts.cli.running.test.testSlotWorkAndBudget · #6dtvm2d4 · term

A slot's work is read as its kind, the codebase it's of (a directory with spaces in it too) and the branch, when it says them; and the machine's slots are TCM_SLOTS when that's set, else what its cores and memory make.
