Mark Murray b9887f5053 Fix some just-noticed problems:
o Allow this to work with "nodevice random" by fixing where the MALLOC pool is defined.

o Fix the explicit reseed code. This was correct as submitted, but in the project branch doesn't need to set the "seeded" bit as this is done correctly in the "unblock" function.

o Remove some debug ifdeffing.

o Adjust comments.
