# Enabling memory overcommit allows to run golang static binaries
# compiled with a recent golang toolchain (>=1.11). Those binaries
# allocate a large amount of virtual memory at init time, and this
# allocation fails in tempest's nano flavor (64MB of RAM)

# follow-up: https://github.com/golang/go/issues/28081)
# TODO(gthiemonge): Remove this call when golang issue is resolved.
