Bug #11613: test_aspawn_too_long_path creates too many processes
https://bugs.ruby-lang.org/issues/11613

* Author: Yui NARUSE
* Status: Open
* Priority: Normal
* Assignee: 
* ruby -v: 
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN
----------------------------------------
At least on FreeBSD, spawn("echo|echo|echo|echo|echo|echo|echo| ...20000 times") success and create 20000 zombie processes.
To prevent this you can add rlimit_nproc: 1 because it tests sh itself, don't test spawned echos.
