I now think that this may be a generic bug in qterminal failing to release storage in /tmp/.
Just now I simply opened a qterminal, did a few listings and noted # df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 984M 20M 965M 2% /tmp I then closed that qterminal and found the /tmp was only using 120K instead of 20M. I hope to have time to investigate further and try the same prodcedure in an instance of lxterminal. For what it is worth, lsof on /tmp shows COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME lsof 1205 root 1w REG 0,27 0 604 /tmp/bug.2 qterminal 6887 ael 20u REG 0,27 892 20 /tmp/#20 (deleted) qterminal 6887 ael 23u REG 0,27 132544 21 /tmp/#21 (deleted) qterminal 6887 ael 26u REG 0,27 223 22 /tmp/#22 (deleted) qterminal 6887 ael 37u REG 0,27 0 492 /tmp/#492 (deleted) qterminal 6887 ael 39u REG 0,27 132 399 /tmp/#399 (deleted) qterminal 6887 ael 42u REG 0,27 0 493 /tmp/#493 (deleted) qterminal 6887 ael 44u REG 0,27 22768 400 /tmp/#400 (deleted) qterminal 6887 ael 45u REG 0,27 0 494 /tmp/#494 (deleted) qterminal 6887 ael 46u REG 0,27 33 401 /tmp/#401 (deleted) qterminal 6887 ael 47u REG 0,27 0 433 /tmp/#433 (deleted) qterminal 6887 ael 52u REG 0,27 0 434 /tmp/#434 (deleted) qterminal 6887 ael 54u REG 0,27 0 435 /tmp/#435 (deleted) That was with several instances of qterminal running.
