* perf(ports): run lsof without blocking on dead network mounts Without -b, lsof stat()s every mounted file system before answering. A hard-mounted network share that stops responding blocks that call in the kernel, so each port scan left an unkillable lsof behind. Pass -b -w to the lsof queries that name no file (port list, process cwd, executable path); their output is unchanged. The -U and +D queries keep stat because -b makes lsof reject named-file arguments. Linear: STA-9017, STA-9716 * perf(ports): name the stuck lsof helper in the comment; plain readiness test name * test: query a known child executable in lsof readiness smoke test

// Why: without -b, lsof stat()s every mount in a forked helper, and a dead network mount blocks
|
|
// that call in the kernel, leaving an unkillable helper process behind on every scan. -w hides the
|
|
// "can't stat()" warnings -b prints. Only for queries that name no file: with -b, lsof rejects
|
|
// file arguments such as `-U <path>` or `+D <dir>`.
