It seems that commit b0bdae7 has completely broken haproxy for me. When
I send a request to haproxy, it just sits there. The backend server
receives nothing, and the client waits for a response.
Running with debug enabled I see just a single line:
00000000:f1.accept(0004)=0005 from [127.0.0.1:63663] ALPN=<none>

MAJOR: tasks: Introduce tasklets.
Introduce tasklets, lightweight tasks. They have no notion of priority,
they are just run as soon as possible, and will probably be used for I/O
later.
For the moment they're used to replace the temporary thread-local list
that was used in the scheduler. The first part of the struct is common
with tasks so that tasks can be cast to tasklets and queued in this
list.
Once a task is in the tasklet list, it has its leaf_p set to 0x1 so that
it cannot accidently be confused as not in the queue.
Pure tasklets are identifiable by their nice value of -32768 (which is
normally not possible).
Issue reproducible with a very simple config:
defaults
mode http
frontend f1
bind :8081
default_backend b1
backend b1
server s1 127.0.0.1:8081
