Transcript in headless image, should flush output more often

[GoogleCodeExporter]

~From Gerardo: 

Hi. I'm working on something, and as part of an update process I have a 
topaz script that fetches information and commits it. The process is 
long, and I'd like to see some progress report, to be sure it's not 
stalled or something. 

The code is using the Transcript, and when ran from topaz, I found the 
result goes to a log file of the form "gemnetobject####glass.log" (I 
guess glass is the username, I'm using the appliance). 

My question is, how can I flush the Transcript so I can use tail -f to 
see the progress? (I'm currently not seeing anything until topaz exits, 
which is too late for progress report). 

An alternative would be a way to print to standard output from the 
script. In this case I would have to change everything to use this 
instead of the Transcript when ran from topaz, but it's not that bad. 

AND 

GsFile stdin 
GsFile stdout 
GsFile stderr 
GsFile stdoutServer 
and basically 
GsFile _getStdFile:onClient: 

with this you can, of course, do: 

GsFile stdout nextPutAll: 'hola!'; cr; flush. 

this is enough for me, thanks!
