+ * chained EFCs form a cycle. Note that this function does
+ * not actually close the file (though it closes all children
+ * as appropriate), as that is left up to the calling
+ * function H5F_try_close().
+ *
+ * Because H5F_try_close() has no way of telling if it is

+ * function serves as both the root of iteration and the
+ * "callback" for the final pass (the one where the files are
+ * actually closed). The code for the callback case is at
+ * the top of this function; luckily it only consists of a
+ * (possible) call to H5F_efc_release().
+ *
+ * The algorithm basically consists of 3 passes over the EFC
+ * tree. The first pass assumes that every reachable file is
+ * closed, and keeps track of what the final reference count
+ * would be for every reachable file. The files are then
+ * tagged as either closeable or uncloseable based on whether
+ * this reference count drops to 0.
+ *
+ * The second pass initiates a traversal from each file
+ * marked as uncloseable in the first pass, and marks every
+ * file reachable from the initial uncloseable file as
+ * uncloseable. This eliminates files that were marked as
+ * closeable only because the first pass assumed that an
+ * uncloseable file would be closed.
+ *
+ * The final pass exploits the H5F_efc_release()->
+ * H5F_efc_remove_ent()->H5F_try_close()->H5F_efc_try_close()
+ * calling chain to recursively close the tree, but only the
+ * files that are still marked as closeable. All files
+ * marked as closeable have their EFCs released, and will
+ * eventually be closed when their last parent EFC is
+ * released (the last part is guaranteed to be true by the
