📄 Description

If we have an error after creating a new sequence but before finding a slot for it, we return without releasing the semaphore. This reduces our parallel sequences and eventually leads to deadlock.

In practice this should never happen because once we have acquired the semaphore, we should always be able to find a slot. However, the code is clearly not correct.
