[HACKERS] jacana hung after failing to acquire random number

jascana (mingw, 64 bit compiler, no openssl) is currently hung on "make 
check". After starting the autovacuum launcher there are 120 messages on 
its log about "Could not acquire random number". Then nothing.


So I suspect the problem here is commit 
fe0a0b5993dfe24e4b3bcf52fa64ff41a444b8f1, although I haven't looked in 
detail.


Shouldn't we want the postmaster to shut down if it's not going to go 
further? Note that frogmouth, also mingw, which builds with openssl, 
doesn't have this issue.


cheers
