I'd imagine that context manager here simply wouldn't cancel the current
task if the lock can be acquired in time:
```
async with lock.acquire(timeout=1.0):
await do_things_with_lock()
```

anyio provides a nice context manager that works in both asyncio and trio:
```
import anyio
async def async_fn():
with anyio.move_on_after(1.0) as scope:
async with lock:
scope.deadline = math.inf
await do_things_with_lock()
```

Note that you can wrap any of those methods with an asyncio.wait_for().
try:
try:
await asyncio.wait_for(lock.acquire(), 1.0)
except asyncio.TimeoutError: # times out after 1 second
print("deadlock!")
return
do_things_with_lock()
finally:
lock.release()
Although
This is already supported with [`asyncio.wait_for()`](
https://docs.python.org/3/library/asyncio-task.html#asyncio.wait_for).
For example: `await asyncio.wait_for(asyncio.Event().wait(), timeout=60)`
