# is_party_alive must not probe the PID with kill -0. POSIX kill(2) is
|
|
# allowed to return EPERM when the caller can't signal the target, and
|
|
# illumos/BSD/macOS honor that — so kill -0 against another user's PID
|
|
# returns nonzero even when the process exists. Linux and Linux-ABI
|
|
# zones (LX-branded) are the outliers that return 0; that's why the
|
|
# bug hid in the test matrix until a native illumos run surfaced it.
|
|
# Discovery now relies on `tmux -S list-clients` alone, which is
|
|
# strictly stronger (filters PID-reuse, dead servers, AF_UNIX impostors).
