I'm still not sure this is going to work, because after exec which returns
immediately, I still have to check that the long operation has finished and
then show the result, and that can take any amount of time.

The process that is exec'ed signals the end of the processing by creating a
file, and in my script I something like this:

while( !file_exists( $signal_end_file ) )
sleep( 1 );

While this loop is going on, I can't do anything else in the scripts
associated with this session.

Is there any other way to check for the end of the operation on the server,
that would not block, for example event based etc.

Thanks,

A
