+This configuration comes from the following blog article:
+
+"How scalable is SCons?  The Electric Cloud Blog"
+http://blog.electric-cloud.com/2010/03/08/how-scalable-is-scons/
+
+    The test build consists of (a lot of) compiles and links. Starting
+    from the bottom, we have N C files each with a unique associated
+    header file. The C files and headers were spread across
+    N/500 directories in order to eliminate filesystem scalability
+    concerns. Both the C files and the header files are trivial: the
+    header only includes stdio.h; the C file includes the associated
+    header and a second, shared header, then defines a trivial
+    function. Objects are collected into groups of 20 and stored into
+    a standard archive. Every 20th object is linked into an executable
+    along with the archive.
+
+The original ElectricCloud implementation is captured in genscons.pl,
+and we just call that script to generate the configuration in a
+"sconsbld" subdirectory.

+import TestSCons
+
+# The values here were calibrated by hand on the ubuntu-timings slave,
+# because the configurations generated by genscons.pl only work if
+# the FILES_PER_DIRECTORY value is a multiple of the COMPILES_GROUPED
+# value, and it didn't seem worth automating that manipulation.
+#
+# The key value below is FILES_PER_DIRECTORY; the other values match
+# the default from the genscons.pl file.  With the values below,
+# it creates a two-deep hierarchy of a single directory with three
+# subdirectories.  Each directory (both parent and subdirectories)
+# contains sixty source files (each of which includes a .h file)
+# that are built into three libraries containing twenty object files
+# each, which are then linked into executables.
+#
+# As of r5143 on 17 August 2010, a value of 60 FILES_PER_DIRECTORY
+# performs a full build in 82.5 seconds on the ubuntu-timings slave.
+# That's more than our "normal" target of 10 seconds or so for the
+# full build, but building anything less than three libraries per
+# directory feels like it makes the test too trivial.
