Title:
  Memory leak

Status in pcsc-lite package in Ubuntu:
  New

Bug description:
  I noticed that pcscd consumes a lot of memory (5GB after 48h since start) in one of my computers (ubuntu 14.04 64-bit pcsc-lite version 1.8.10.)
  In debug mode pcscd shows a lot of USB "device removed" notifications:

  00000102 hotplug_libudev.c:594:HPEstablishUSBNotifications() Device removed
  00001297 hotplug_libudev.c:269:get_driver() Looking for a driver for VID: 0x1D6B, PID: 0x0002, path: /dev/bus/usb/001/001
  [cut - long list of usb devices]
  00000246 hotplug_libudev.c:269:get_driver() Looking for a driver for VID: 0x03EB, PID: 0x2044, path: /dev/bus/usb/001/067
  00022327 winscard_svc.c:319:ContextThread() Received command: CMD_GET_READERS_STATE from client 5
  00500329 winscard_svc.c:319:ContextThread() Received command: CMD_GET_READERS_STATE from client 5
  00500341 winscard_svc.c:319:ContextThread() Received command: CMD_GET_READERS_STATE from client 5

  Flood of "device removed" messages was caused by some broken USB
  device (not card reader - CDC-ACM device), but it doesn't explain why
  pcscd allocated 5GB of memory. Is it some memory leak in pcscd?
