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

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could 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 state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.
