/**
 * The dbpf open cache is used primarily to manage open
 * file descriptors to bstream files on IO servers.  PVFS
 * currently uses a lazy style of creating the actual datafiles for
 * bstreams.  Only on the first write to a bstream is the file
 * actually created (opened with O_CREAT).  This means that if a
 * read of a bstream that hasn't been written should somehow occur,
 * an ENOENT error will be returned immediately, instead of allowing
 * a read to EOF (of a zero-byte file).  For us, this is ok, since
 * the client gets the size of the bstream in the getattr before doing
 * any IO.  All that being said, the open_cache_get call needs to
 * behave differently based on the desired operation:  reads on
 * files that don't exist should return ENOENT, but writes on files
 * that don't exist should create and open the file.
