BTW, it is correct for sockets - socket_handlers is defined in 
cpukit/libnetworking/rtems/rtems_syscall.c
Note that lseek_h handler set to NULL there, and lseek() in 
libcsupport/src/lseek.c return ENOTSUPP in this situation instead on 
ESPIPE. So we should either explicitly implement lseek for sockets 
returning ESPIPE (I prefer this), or return ESPIPE in lseek.c instead of 
ENOTSUPP.
