samskalicky edited a comment on issue #13438: libc getenv is not threadsafe URL: https://github.com/apache/incubator-mxnet/issues/13438#issuecomment-444604976 @larroy We were already using locks inside the handlers. setenv uses a lock in libc around modifying the environment. This doesnt change anything. Are you suggesting that we dont use an EnvVar to pass the OMP_NUM_THREADS=1 to subsequent processes? What do you think the impact will be the other processes that are using MXNet using more threads? Was there a conscious decision to use an EnvVar to limit OMP_NUM_THREADS in subsequent processes?
