Windows server runs out of memory when querying PACS

My test system runs out of system memory, causing PostgreSQL to fail, when querying PACS for radiographic or mammographic images. This is related to how the extractor is run in the openrem_orthanc_config_windows.lua file:

Replacing this line:

os.execute('start /b ' .. python_executable .. ' ' .. python_scripts_path .. import_script .. ' ' .. temp_file_path)

With this line:

os.execute(python_executable .. ' ' .. python_scripts_path .. import_script .. ' ' .. temp_file_path)

Fixes the issue for me in the following section of openrem_orthanc_config_windows.lua:

     -- Call OpenREM import script. Runs as orthanc user in linux, so log files must be writable by Orthanc
     -- Run in detached mode, so long imports don't lead to network problems
     if (use_postgres) then
        if (use_windows_execute) then
           os.execute('start /b ' .. python_executable .. ' ' .. python_scripts_path .. import_script .. ' ' .. temp_file_path)
        else
           os.execute(python_executable .. ' ' .. python_scripts_path .. import_script .. ' ' .. temp_file_path .. ' &')
        end
    else
        os.execute(python_executable .. ' ' .. python_scripts_path .. import_script .. ' ' .. temp_file_path)
    end

The above section can be simplified, and the comment changed, because this file only applies to Windows.
