verified.

BTW: postmaster -d 5
will give you verbose output.

it's a cygserver problem. But I haven't checked yet if it's just
too much connections (postgresql checks at init some max_connections 
params from 500 down to 10), still too less memory or if it's the dup 
problem.
dup(0) => Bad file descriptor ???

sometimes the single select works. sometimes it crashes after you do 
some inserts.
unfortunately the regression testsuite doesn't handle this case.
