Shouldn't we just open the file here instead of the additional touch above?

Well technically yes, but then the touching wouldn't be async.

Well, the fopen isn't async anyway? I guess we'd have to add the function to Handle to have it really async?

Well, fopen isn't async, but afaik there is no way to obtain a lock using any of the native async libs supported by amphp.
I thought it'd be nice if we could make at least the touch part of the fopen async.

@trowski What's your opinion here?

I'm rather uncomfortable introducing anything that can block when it could be rolled into a simple Task executed using parallel.

Should we check for the file being deleted here and recreate it? I guess it could make sense to delete after unlocking, but not in every case (i.e. only if it's a separate lock file).

I really don't think this is the place for such logic
