Steve Loughran commented on SLIDER-584:
---------------------------------------
SLIDER-86 reworked stdout/stderr forwarding for the python scripts so they'd be
consistent across windows and unix. Now they spin waiting for lines and
printing them
{code}
while not finished:
(line, done) = read(src, line)
info(line)
line = ""
{code}
It could just be some concurrency logic here: the line isn't completely parsed
before the {{finished}} bit is set, so the handler should add a teardown
sequence that just does a read & print until the end of the file is hit, at
which time the thread finishes.
One caveat: windows does behave differently here.
