I've done some tests using the text driver and the lcdproc client, it
doesn't seem to leak memory. Between 2PM and 6PM on Friday, memory
use augmented by 12 kB, but has been stable since.

I'm on linux kernel 2.2.20 (debian) using only the text driver
directed to /dev/null.

Could you specify what are the conditions that make LCDd leak that
much memory, please?

Here's a summary of my tests:
[gfk@ali stable-0-4-4]$ ./configure --enable-drivers=3Dtext
[gfk@ali stable-0-4-4]$ make
[gfk@ali stable-0-4-4]$ server/LCDd -c ../LCDd-0-4-4.conf > /dev/null &
