If I'm not completely blind, there is no suspicous ERESTARTSYS in
PF_INET:SOCK_STREAM path.
Anyway even if it was returned by kernel syscall, glibc should put it in errno
and return -1 (since it is >= -4095 and < 0). He sees it in the accept retval.
Something rotten, probably broken/racy ?ntpl? implementation of syscalls or
somewhat?
