When in isolated mode, SPEs have access to an area of persistent storage, which is per-SPE. In order for isolated-mode apps to communicate arbitrary data through this storage, we need to ensure that isolated physical SPEs can be reused for subsequent applications. Add a file ("recycle") in a spethread dir to enable isolated-mode recycling. By writing to this file, the kernel will reload the isolated-mode loader kernel, allowing a new app to be run on the same physical SPE. This requires the spu_acquire_exclusive function to enforce exclusive access to the SPE while the loader is initialised.
