## Known Issues
* Does not work on x86 platforms (including the Android cuttlefish emulator).
+* If heapprofd is run standalone (by running `heapprofd` in a root shell, rather
+ than through init), `/dev/socket/heapprofd` get assigned an incorrect SELinux
+ domain. You will not be able to profile any processes unless you disable
+ SELinux enforcement.
+ Run `restorecon /dev/socket/heapprofd` in a root shell to resolve.
