I tried this again with the same result. This time I made core dumps of:

1. the hogger "udisks-daemon"
2. the hogger "udisks-helper-modify-partition"
3. the two hogger's parent process, which is also "udisks-daemon"

I made them with kill -STOP pid && gcore pid

Title:
  usb-creator format disk causes udisks-daemon hogging mem and cpu

Status in “udisks” package in Ubuntu:
  New

Bug description:
  Note: I restarted my system to get my computer working properly. These
  attachments may be useless.

  I was trying to create a bootable usb stick with usb-creator. I
  clicked "format disk".

  (What you expected to happen)

  I expect this utilty to wipe my usb stick so that the iso can be
  installed onto it.

  (What happened instead)

  It said something like "dbus did not send a reply", and the system was
  frozen. I got into the tty and ran top there, finding that udisks-
  daemon is hogging both cpu and memory, and another process udisks-
  helper-modify-partion hogging only cpu.

  Output from top

  4343 root 20 0 8391m 3.1g 460 R 99.9 81.3 7:41.24 udisks-daemon
  8593 root 20 0 20060 504 408 R 99.9 0.0 7:41.65 udisks-helper-m

  the second process was truncated by top somehow

  I have a dell inspiron 3421, which came with a ubuntu. I upgraded it
  to 13.10. I have udisks 1.0.4-8ubuntu1, usb-creator-gtk 0.2.50.1, in
  case these are useful

  (PS My English is not very good. Edit my post if you wish.)
