-// This class manages the crash minidumps.
-// On Android, because of process isolation, each renderer process runs with a
-// different UID. As a result, we cannot generate the minidumps in the browser
-// (as the browser process does not have access to some system files for the
-// crashed process). So the minidump is generated in the renderer process.
-// Since the isolated process cannot open files, we provide it on creation with
-// a file descriptor where to write the minidump in the event of a crash.
-// This class creates these file descriptors and associates them with render
-// processes and take the appropriate action when the render process terminates.
