GIL release

[Alastair Basden]

Hi,
Does anyone know whether there is a way for a python thread to release
the global interpreter lock, and let all other threads have a chance at
running before re-acquiring it? Does the thread scheduling follow a
round-robin method?

Thanks,
agb.

The thread itself are scheduled by the OS ... the access to the GIL is
managed by 'cooperative scheduling'.

Re: GIL release

Do you mean in Python or in C ?

In C this is described in details in the documentation. In Python, I
don't think there is a way ! If you want to do so you'll want to use a
micro sleep ...
