Comment 3 for bug 581173

This affects me as well. Here is what strace says:

open("/dev/shm/pulse-shm-87918442", O_RDONLY|O_NOFOLLOW|O_CLOEXEC) = 10
fstat(10, {st_mode=S_IFREG|0400, st_size=67108904, ...}) = 0
mmap(NULL, 67112960, PROT_READ, MAP_SHARED, 10, 0) = 0x7dd86cb71000
close(10) = 0
kill(5289, SIG_0) = 0
munmap(0x7dd86cb71000, 67112960) = 0
open("/dev/shm/pulse-shm-4214229396", O_RDONLY|O_NOFOLLOW|O_CLOEXEC) = 10
fstat(10, {st_mode=S_IFREG|0400, st_size=67108904, ...}) = 0
mmap(NULL, 67112960, PROT_READ, MAP_SHARED, 10, 0) = 0x7dd86cb71000
close(10) = 0
kill(5289, SIG_0) = 0
munmap(0x7dd86cb71000, 67112960) = 0

Also, the process as allocated 500M of physical memory (1.7TB virtual) and is spinning on one CPU. The problem *might* be related to the gmail checker plugin in Chrome. At least I didn't notice the problem before installing that extension.
