Production incident: autorip's poll loop called scsi::reset() on a wedged BU40N USB drive. The Linux SG_SCSI_RESET ioctl blocked indefinitely (kernel SCSI subsystem waiting for a bus-wedged device to ack a reset that will never come). Caller's poll loop hung for 60+ seconds before manual intervention. scsi::reset() now spawns a detached worker for the platform-specific reset and bounds the caller's wait via mpsc::recv_timeout. Default 30 s (DEFAULT_RESET_TIMEOUT_SECS); reset_with_timeout(device, dur) exposes the bound for callers that want a different value. Returns DeviceResetFailed on timeout. Worker thread keeps running until the kernel eventually unblocks — leaks one OS thread per hard wedge, but the daemon stays responsive instead of hanging forever. Follow-up flagged for 0.13.2: USB-attached drives wedge at the USB Mass Storage layer below SCSI; SG_SCSI_RESET doesn't help. A scsi::usb_reset(path) using USBDEVFS_RESET is the proper escalation.
