-// This provides a wrapper around system calls which may be interrupted by a
-// signal and return EINTR. See man 7 signal.
-// To prevent long-lasting loops (which would likely be a bug, such as a signal
-// that should be masked) to go unnoticed, there is a limit after which the
-// caller will nonetheless see an EINTR in Debug builds.
-//
-// On Windows, this wrapper macro does nothing.
-//
-// Don't wrap close calls in HANDLE_EINTR. Use IGNORE_EINTR if the return
-// value of close is significant. See http://crbug.com/269623.
