What changed in v4.3.6 — 2026-09-04

Round 8 of the sweep. One finding, and it is a sentence I wrote in 4.3.5 that was not true.

Fixed

• Disposing a VM now frees a guest that is only sleeping. A task can be waiting in three ways. A descriptor wait ends because Dispose closes the descriptor under it, and an interrupt wait because a disposed VM answers it — but a deadline was a plain sleep, which nothing interrupts. So "disposing gives the thread back", which guide 14 has promised since 4.3.5, held for two waits out of three: measured, a task that asked for 20 000 ms held the host's thread for 19 845 ms after its VM was gone. It waits on the VM's own signal now — 6 ms in the same measurement — and guide 14 names all three waits rather than the two that happened to work.

  A guest sleeping is exactly the hung script a host has no other way to stop, so this was the case the contract exists for, missing for the second round running.
