This is the same testcase I pasted last week:

  $ ./x 40000
  pipe capacity: 65536
  write: writable 1, 40000 25536
  write: writable 1, SIGALRM 24576 960
  write: writable 0, SIGALRM 512 448
  write: writable 0, SIGALRM 256 192
  write: writable 0, SIGALRM 128 64
  write: writable 0, SIGALRM 64 0
  write: writable 0, SIGALRM -1 / Interrupted system call

So why does it not get into the last else case after calling
pipe_data_available()?  Do you get a different return value
from pipe_data_available()? If so, what and why?
