Package: hamster-applet
Version: 2.30.1-1
Severity: normal
Just attach to the process with strace and you will see how it is
looping over a non-blocking read() call.
On my system this process causes over 140 wakeups per second.
read(4, 0x96739a0, 4096) = -1 EAGAIN (Resource temporarily unavailable)
gettimeofday({1274622380, 388081}, NULL) = 0
poll([{fd=5, events=POLLIN}, {fd=4, events=POLLIN}, {fd=11, events=POLLIN|POLLPRI}, {fd=8, events=POLLIN}, {fd=15, events=POLLIN|POLLPRI}, {fd=16, events=POLLIN|POLLPRI}, {fd=17, events=POLLIN|POLLPRI}, {fd=20, events=POLLIN|POLLPRI}, {fd=19, events=POLLIN|POLLPRI}, {fd=7, events=POLLIN|POLLPRI}, {fd=18, events=POLLIN|POLLPRI}, {fd=21, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN}, {fd=23, events=POLLIN}, {fd=14, events=POLLIN}], 15, 6) = 0 (Timeout)
gettimeofday({1274622380, 395840}, NULL) = 0
fd 4 is the X protocol socket.
