<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">I did a small valgrind test with git HEAD:<br>
1. turn on, make 5 calls or so<br>
2. leave FS on for the night (without calls)<br>
3. shut it down cleanly in the morning<br>
<br>
During execution, some "Warning: invalid file descriptor -1 in syscall<br>
close()" (4-5 for each call + some extras).<br>
<br>
After shutting down, something strikes me in the vg.log file:<br>
"definitely lost: 173,407,885 bytes in 84,680 blocks"<br>
<br>
Is this normal?<br>
