RE: Rand_status so slow on windows

[Steven Reddie]

RAND_status will trigger seeding of the PRNG if it has not been initialised.  On Windows the entropy gathering can take a long time due to the heap walking and performance counter accesses.  Whether it completes in a reasonable time or takes much longer can depend on current system activity and what performance counters have been installed.  Although adding entropy data with RAND_add increments the entropy count it doesn't set the initialized flag that rand_status uses.  I believe the only ways to fix this are: 1. Drop in your own PRNG implementation with RAND_set_rand_method 2. Drop in your own ENGINE that provides a PRNG implementation with RAND_set_rand_engine 3.
