Downloaded latest Ubuntu 18.0.4 build this morning from https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1804-latest.tgz, which unpacks to mongodb-linux-x86_64-ubuntu1804-4.3.3-713-g56655b0 and identifies itself in the log file as having been built from a commit made yesterday:

Tried SIGUSR2 and then 10 seconds later SIGSEGV to confirm that I was actually sending a signal
> date; killall -SIGUSR2 mongod; sleep 10; date; killall -SIGSEGV mongod Tue Mar 3 08:15:37 EST 2020 Tue Mar 3 08:15:47 EST 2020
Log shows that the SIGSEGV at 08:15:47 worked but the SIGUSR2 10 seconds earlier at 08:15:37 had no effect

I've also tried on a recent MacOS build and couldn't get SIGUSR2 to work.
