Tee and file redirections are very slow to write anything.

[Hamish McIntyre-Bhatty]

Hi there,

I found recently when trying to save output from a script for later 
inspection that "tee" and file redirections seem to have massive delays 
when run in Cygwin - usually nothing is written to file or stdout until 
after the command has finished - not very helpful.

I'm running a bash script with the following cmdlines:

"bash ./path/to/script.sh > stdout.log"

and:

"bash ./path/to/script.sh | tee stdout.log"

Both of them result in no writes to the file (or stdout in the second 
case) until the command is finished, and as this script takes minutes to 
run, it's not very helpful. I'm running these commands from bash in Mintty.

Is there any configuration I need to do, or have I potentially 
discovered a bug? IIRC there have been some changes in the dev version 
of Cygwin relating to file I/O so perhaps this is already fixed?

Hamish
