limit l1 2
family f5

In the 5 series, this has been extended to Family's.
When a family is limited, the child tasks are unconstrained. In this case, only two families can run at a time. All the tasks in the family can start at once
Ensure that only 2 Family can run in parallel
suite test
limit fam 2
family f1
inlimit -n fam
task t1
task t2
endfamily
family f2
inlimit -n fam

task t2
endfamily
family f3
inlimit -n fam
task t1
task t2
endfamily

In this case, we want family limits, but also want to constrain the tasks, such that one task in the active family can run.
Limit Family and Task. Here one Family can run, and one task
