The write operation at flow_graph_manager_test.go:209 pertains to a variable that appears to be unrelated to gopsutil:

The definition of this variable:

To Reproduce
gopsutil version we are using: github.com/shirou/gopsutil/v3 v3.22.9

Expected behavior
No data race.

Environment (please complete the following information):

• Windows: [paste the result of ver]
• Linux: [paste contents of /etc/os-release and the result of uname -a]
• Mac OS: [paste the result of sw_vers and uname -a
• FreeBSD: [paste the result of freebsd-version -k -r -u and uname -a]
• OpenBSD: [paste the result of uname -a]

Is there any reproducible short code? And does it reproduce using the latest version(v3.23.6)?
