This data file is a html file containing one table with 5 columns and 10,000
rows filled with random data.

How to reproduce ?

1. Open Calc after compiling from latest git master (5.1.0.0.alpha+)
2. Go to Sheet > Link to External Data
3. Open the attached file using browse button of the External Data dialog
4. Choose Automatic for "Select Language to use for import"
5. Select "HTML_1" in Available Tables/Ranges
6. Check the checkbox "Update every" and set the update interval to 5 seconds.
7. Click OK.
8. Now observe the memory usage of soffice.bin using your favorite tool.

What I observed :

The memory usage increases about 90 to 100 MB every time the auto update of
data occurs.

Here is what I observe in top command for soffice.bin process after letting
Calc run for more than 20 minutes.
  PID USER    PR NI   VIRT   RES    SHR  S  %CPU %MEM     TIME+ COMMAND
21136 dennis  20 0 13.866g 0.013t  20228 S  59.3 41.6  19:39.23 soffice.bin


PS: The attached data file is basically a html file containing one table with 5
columns and 10,000 rows filled with random data.
