+ tests/nap.h: use an adaptive delay to avoid ctime update issues
+ The recent change in nap.h (5191133e) decreased the probability of lost
+ races to about a third, however such problems could still be observed
+ in virtual machines and openSUSE's OBS.
+ Before, nap() detected the needed time once empirically and then used
+ that delay (together with a small correction multiplier) in further
+ calls. This problem has been reported and discussed several times,
+ including guesses about possible kernel issues:
+ https://lists.gnu.org/archive/html/bug-gnulib/2013-04/msg00071.html
+ http://lists.gnu.org/archive/html/coreutils/2012-03/msg00088.html

+ https://lists.gnu.org/archive/html/bug-gnulib/2009-11/msg00007.html
+ Now, nap() avoids the race alltogether by verifying on a reference
+ file whether a timestamp difference has happened.
+ * tests/nap.h (nap_fd): Define file descriptor variable for the
+ witness file.
+ (nap_works): Change return value to bool. Change passing
+ the old file's status by value instead of by reference as this function
+ does no longer update that timestamp; rename the function argument from
+ st to old_st. Remove the local variables cdiff and mdiff because that
+ function now returns true/false instead of the precise delay.
+ (guess_delay): Remove function.
+ (clear_tmp_file): Add new function to close and unlink the witness file.
+ (nap): Instead of re-using the delay which has been calculated during
+ the first call, avoid the race by actually verifying that a timestamp
+ difference can be observed on the current file system. Use an adaptive
+ approach for the delay to minimize execution time. Assert that the
+ maximum delay is <= ~2 seconds, more precisely sum(2^n) from 0 to 30
+ = 2^31 - 1 = 2.1s.
+ Use atexit to call clear_tmp_file when the process terminates.
