Good to know, I updated the patch.

BTW, I also noted that the test sometimes takes longer than usual,
causing the estimated remaining time to go up:

test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (5 out of 50 , remaining: 00:29)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (6 out of 50 , remaining: 00:25)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (7 out of 50 , remaining: 00:22)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (8 out of 50 , remaining: 00:20)

sp----em-- OK (13 out of 50 , remaining: 00:16)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (14 out of 50 , remaining: 00:15)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (15 out of 50 , remaining: 00:14)
test 584...[HTTP GET using pipelining (nonzero length after zero length)]
sp----em-- OK (16 out of 50 , remaining: 00:14)

I do not know what's causing this yet and it may have nothing to
do with the problem.

Unfortunately runtests.pl's "-rf" option doesn't properly work when
running the same test multiple times. The test number is used as hash key,
so only the last measurement is stored until the end.
