Erlangで浮いたプロセスを調べる方法

% erl
Erlang/OTP 19 [erts-8.1] [source] [64-bit] [smp:4:4] [async-threads:10] [kernel-poll:false]

Eshell V8.1  (abort with ^G)

%% 1) まずプロセス数を調べる
1> Before = processes().
2> length(Before).
26

%% 2) 次に調べたい処理をする（通常はもっと複雑な処理）
3> Loop = fun(F) -> timer:sleep(100), F(F) end.
4> LeakPid = spawn(fun() -> Loop(Loop) end).
<0.62.0>

%% 3) もう一度プロセス数を調べる
5> After = processes().
6> length(After).
27

%% 4) 2回調べたプロセス数の差分を取る
7> Delta = After -- Before.
[<0.62.0>]

%% 5) 詳細を見る
