/**
 * allocates space but does NOT add it to the cache list due to synchronization issues. Basically
 * the caller mustn't hold their monitor when calling allocate, as a flush may result in one or more
 * other files being flushed which results in their monitor being taken, and we've got an A->B and
 * B->A classic deadlock situation. However, we must keep the file's cache and our cache in step.
 * It is not acceptable to have an entry inserted into our records but not in the file's as this
 * then screws up the flush algorithm (which assumes that if it finds an entry in our list, a flush
 * of that file is guaranteed to release space). Therefore we add the cache entry in addCacheSpace
 * so that the caller can safely do this while synchronised firstly on its monitor and then we can
 * sync on our. Hence we only ever get A->B monitor grabs which won't deadlock
