I put my modif for basetransform with the sleep and some printf to show the
potential race condition. With the pipeline and doing ctrl-c, you should be
able to see that sometime, the change state is occuring while the buffer alloc
function is also running.

With the patch, things look correct.

About the patch : I am not sure it will synchronize anything new, since the
patch do a stream lock on the next element pad (from the current chain function
of an upstream element). So, I think this is the same thread anyway that do the
buffer alloc and the chain itself.
