the previous approach of acquiring LOCK_SETEUID per-thread serialized the seteuid calls but left a window where other threads inherited euid=0 while the mutex was held. Open the ICMP raw socket once during single-threaded initialization in spine.c main(), before any worker threads start. Store it as a global (icmp_socket). ping_icmp() now dup()s that fd per call so each thread has an independent fd for select()/setsockopt()/close() without interfering with other threads. All seteuid()/LOCK_SETEUID blocks are removed from ping_icmp(). If the socket could not be opened at startup, icmp_avail is set to FALSE and the poller falls back to UDP ping as before.
