$ seq 10000 | wc
  10000   10000   48894

48894 is less than default --block-size (1M), so the behaviour is as expected: Spawn only one.

Not a bug.

Before commit bbc9a53ea5fc746a0a3ef7e8733dfcd61ff05eea

seq 10000 |src/parallel --pipe -j24 sleep 10

would spawn 24 processes as counted by something like

pgrep sleep | wc

After aforementioned commit, only 1 process is spawned.
