On CRAN, valgrind turns up the following error about
Syscall param epoll_ctl(event) points to uninitialised byte(s). It appears to be an issue with the version of libuv we're using and will require a libuv update.https://github.com/libuv/libuv/commit/0813f5b97afe086a7b4d827774605b1f2e99191c#diff-ef6a692d0a1d5779d26d4f57afcf3d42
