"procid" implies "process ID", "processor (CPU?) ID", or "`runtime.p.id`". It is none of these things. Instead, `procid.Current()` returns the caller's host thread ID; almost every caller relies on this property. Rename the package accordingly. Nit: Replace "system thread identifier" with "host thread ID". "System" is needlessly vague in a setting where many callers will also have an unrelated application thread ID, and "identifier" is a guess at what is abbreviated by "thread ID" - but cf. gettid(2), "NAME: gettid - get thread identification".
