Yes, the server. It's in a tight loop. This is all it's doing. Thanks, I'll
look into this.
clock_gettime(0, 0xbfffded8) = -1 ENOSYS (Function not
implemented)
gettimeofday(NULL, {300, 0}) = 0

implemented)
gettimeofday(NULL, {300, 0}) = 0
clock_gettime(0, 0xbfffded8) = -1 ENOSYS (Function not
implemented)
gettimeofday(NULL, {300, 0}) = 0
clock_gettime(0, 0xbfffded8) = -1 ENOSYS (Function not
implemented)
gettimeofday(NULL, {300, 0}) = 0
clock_gettime(0, 0xbfffded8) = -1 ENOSYS (Function not
implemented)
gettimeofday(NULL, {300, 0}) = 0
