Buffering in PoCo::Child

[Mike Schroeder]

We have a POE app that reads multiple input files, reformats them and 
the posts them to various binaries wrapped with PoCo::Child that in turn 
load the data into our underlying system.  The problem we are running 
into is that PoCo::Child seems to be buffering two or three records at a 
time.  Sometimes we have interdependencies between records going into 
various loaders, so we need these to be unbuffered. 

In looking at PoCo::Child, I see how it uses POE::Wheel::Run, which in 
turn uses POE::Driver::SysRW and that Driver::SysRW has a flush() method.

Do I need to patch PoCo::Child's write() to flush() after each write()? 
Or is there some setting or a better way to get unbuffered writes to 
PoCo::Child?


Thanks in advance for any advice.
