 ### Being careful with signals
 
-The `liburcu-signal` library uses signals internally. The signal handler is
-registered with the `SA_RESTART` flag. However, these signals may cause
-some non-restartable system calls to fail with `errno = EINTR`. Care
-should be taken to restart system calls manually if they fail with this
-error. A list of non-restartable system calls may be found in

 except those setup with `sigaltstack(2)`, with `liburcu-memb` and
 `liburcu-mb`. Be careful, however, to disable these signals
