Task_t considered harmful
Ever since installing 10.12.1, I've been having a bunch of processes randomly entering a quasi-paused SIGSTOP-ish state (neither closable, apps not "bouncing" (loading) and just not responding. Running Instruments, correlating logs and such doesn't identify any clear cause.  I'm having to `sudo kill -CONT -1` in order to get things moving again. I'm wondering if it's related to XNU mitigations or just some spurious "system configuration entropy" on my box.
