Child suspend/resume

[Justin Hibbits]

Hi Alexandr,

Thanks.  I got another confirmation that it didn't work, and may have
found the cause.  I have another patch that you can find at
https://phabric.freebsd.org/D590 which fixes a typo that I had made.
Could you try that?

(Added current@ so everyone else sees this as well).

Thanks!

- Justin
