The QEMU project is currently considering to move its bug tracking to anoth=
er system. For this we need to know which bugs are still valid and which co=
uld be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the st=
ate back to "New" within the next 60 days, otherwise this report will be ma=
rked as "Expired". Or mark it as "Fix Released" if the problem has been sol=
ved with a newer version of QEMU already. Thank you and sorry for the incon=
venience.

Title:
  Reading /proc/self/task/<pid>/maps is not remapped to the target

Status in QEMU:
  Incomplete

Bug description:
  Seeing this in qemu-user 3.1.0

  The code in is_proc_myself which supports remapping of /proc/self/maps
  and /proc/<pid>/maps does not support remapping of
  /proc/self/task/<pid>/maps or /proc/<pid>/task/<pid>/maps. Extending
  is_proc_myself to cover these cases causes the maps to be rewritten
  correctly.

  These are useful in multithreaded programs to avoid freezing the
  entire program to capture the maps for a single tid.
