repeat calls to getentrypy() with the same pid likely indicate reseeds.
Since we assume the PRNG above is doing "something old, something new"
folding, shortcut and do fewer repeats through the timing loop.

unbreak last commit - but same intent, make re-seed less expensive
j should be an int, like repeat
fix oops, accidental delete.. darn copying of files between machines
getentropy for osx and solaris. will be needed for a portable release
Remove undocumented _des_crypt() interface and its companion header file,
which had never been installed, so it's unlikely something ever used this
in the last 15~20 years.
