+# Since we want to make sure that iostat responds correctly as pools appear and
+# disappear, we run it in the background and capture its output to a file.
+# Once we're done, we parse the output and ensure it matches what we'd expect
+# from the operations we performed.
+#
+# Because iostat is producing output every interval, it may produce the "same"
+# output for each step of the change; in fact, we want that to make sure we
+# don't miss anything. So, we describe what we expect as a series of "chunks".
+# Each chunk is a particular kind of output, which may repeat. Current known
+# chunk types are:
+#
+# NOPOOL: the text "no pools available"
+# HEADER: three lines, starting with "capacity", "pool" and "----" respectively.
+#         (the rough shape of the normal iostat header).
+# POOL1: a line starting with "pool1" (stats line for a pool of that name)
+# POOL2: a line starting with "pool2"
+# POOLBOTH: three lines, starting with "pool1", "pool2" (either order) and
+#           "-----" respectively. (the pool stat output for multiple pools)
+#
+# (the parser may produce other chunks in a failed parse to assist with
+#  debugging, but they should never be part of the "wanted" output See the
+#  parser commentary below).
+#
+# To help recognise the start of a new interval output, we run iostat with the
+# -T u option, which will output a numeric timestamp before each header or
+# second-or-later pool stat after the header.
+#
+# To keep the test run shorter, we use a subsecond interval, but to make sure
+# nothing is missed, we sleep for three intervals after each change.
