Fixed t/86gofer_fail tests to be less likely to fail falsely.
Corrected timeout example in docs thanks to Egmont Koblinger.

DBI::Profile changes:
Don't profile DESTROY during global destruction.
+ Added as_node_path_list() method.
DBI::ProfileDumper changes:
Don't write file if there's no profile data.
Uses full natural precision when saving data (was using %.6f)

+
+Returns the collected data ($dbh->{Profile}{Data}) restructured into a list of
+array refs, one for each leaf node in the Data tree. This 'flat' structure is
+often much simpler for applications to work with.
+
+The first element of each array ref is a reference to the leaf node.
+The remaining elements are the 'path' through the data tree to that node.
+
+For example, given a data tree like this:
+
+ {key1a}{key2a}[node1]
+ {key1a}{key2b}[node2]
+ {key1b}{key2a}{key3a}[node3]
+
+The as_node_path_list() method will return this list:
+
+ [ [node1], 'key1a', 'key2a' ]
+ [ [node2], 'key1a', 'key2b' ]
+ [ [node3], 'key1b', 'key2a', 'key3a' ]
+
+The nodes are ordered by key, depth-first.
+
+The $node argument can be used to focus on a sub-tree.
+If not specified it defaults to $dbh->{Profile}{Data}.
+
+The $path argument can be used to specify a list of path elements that will be
+added to each element of the returned list. If not specified it defaults to a a
+ref to an empty array.
