This may have to do with unreliable signal handling (SIGCHLD in this
case) in Guile:

  https://lists.gnu.org/archive/html/guile-devel/2013-07/msg00004.html

shepherd.scm has a hack to mostly work around it, but it’s not always
sufficient as evidenced by occasionally failures of the respawn test:

  http://bugs.gnu.org/23811

Does it frequently fail to respawn?
