supervisor empty logfile

I've been messing around supervisor logfile capabilities. The program writes to stdout:

ruby sample.rb
>>0.9668821900023237 [tps] 
>>61.91346356232367 [tps] 
>>Heartbeat....
>>58.84168122263758 [tps] 
>>Heartbeat....

When I run it from supervisor, I've got log files created, but stdout_logfile is always empty. When I mess something in sample.rb, so that I have any kind of exception, it is successfully written to stdout_logfile due to redirect_stderr.

Supervisor configuration file:

[program:sample]
priority=50
command=/usr/bin/ruby sample.rb
numprocs=1
directory=/home/myapp/myapp
autorestart=true
autostart=true
startsecs=10
stopwaitsecs=90
redirect_stderr=true
stdout_logfile=/var/log/sample.out.log
user=myapp

Why I see no output on stdout_logfile?

This issue is solved by simply calling flush on stdout.

puts "hello world"
$stdout.flush
