This is a bug in tst-skeleton.c IMO, it should allocate a buffer large enough
for the test to succeed, but small enough that you still get output as quickly
as possible in the even of a crash.

Thus tst-skeleton.c needs to be enhanced to allow the test to define the size
of the stdout buffer it needs and then that can be allocated and passed to
setvbuf?
