Introduces two macros:
- `SLEEP` to perform a nanosleep call with the specified amount of
time expressed as nanoseconds;
- `SLEEP_AND_GOTO` does the same of the above but adds also a `goto`
to the specified label.
Example of usage:
SLEEP_AND_GOTO(1000000L,retry)
is the same as
{
/* Sleep for 1ms */
struct timespec ts;
ts.tv_sec = 0;
ts.tv_nsec = 1000000L;
nanosleep(&ts, NULL);
goto retry;
}

I think this could improve code readibility: there are several places (not many) where there is a code like fhis:
such code performs a sleep and a jump, and is used when asking for a lock acquisition.
Cannot we wrap the code in a macro so that the above becomes:
Could this improve source code readibility and avoid duplication of code?
