It seems that when you run OpenOffice.org as a "server" using the "accept"
command line it is possible to make it leak memory by repeatedly running a
Python script that connects with PyUNO, writes some tabular data into a Writer
document, and then saves it as a PDF file. Our code is leaking around 1MB per
script, but here is an example that seems to cause soffice.bin to leak around
about 0.2MB per invocation:
import uno

from com.sun.star.util import CloseVetoException

local_context = uno.getComponentContext()
local_service_manager = local_context.ServiceManager
resolver = local_service_manager.createInstanceWithContext(
'com.sun.star.bridge.UnoUrlResolver', local_context)
connection_string = \
"uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext"
remote_context = resolver.resolve(connection_string)
remote_service_manager = remote_context.ServiceManager
desktop_class = 'com.sun.star.frame.Desktop'

remote_context)

text.insertTextContent( cursor, table, 0 )
