+Description: fix test to take account of larger page sizes on ppc64el
+ The test_default_wait/TestDefaultWait test assume that a single read
+ can definatly switch a "full" pipe to one which will poll writable.  The
+ kernel optimises for IO size by delaying the writable status until a
+ complete buffer slot is available; these are the system page.  The test
+ already exhibits this by using large IOs compared to the common 4K page
+ size, but this is not sufficient in the face of the 64K page sizes on
+ ppc64el.  Up this to 64k which represents the biggest page size available
+ in the kernel.
