Ah, finally caught 665 in action!

665 is the .1 second poller process which is polling an ioctl call on file descriptor 15.

Acoording to lsof fd 15 is hooked to:

Code:

contentLi  665 root   15u   CHR      222,0              329 /dev/buttons

See how all these tools work together?

So now we see that when the page bar gets tweaked 665 does something about it.

Code:

ioctl(15, 0x80046207, 0xbf3ffb0c)       = 0
nanosleep({0, 100000000}, NULL)         = 0
ioctl(15, 0x80046207, 0xbf3ffb0c)       = 0
kill(666, SIGRTMIN)                     = 0
kill(666, SIGRTMIN)                     = 0
nanosleep({0, 100000000}, NULL)         = 0

It does the kill 32 on process 666 which we saw in the earlier straces.
