-// Heap snapshots are always saved in the temp directory, and have a regular
-// naming convention. This module provides helpers for working with heap
-// snapshot files in a safe manner. Because we attempt to avoid unnecessary
-// copies of the heap snapshot files by checking the local filesystem for a heap
-// snapshot file with the given snapshot id, we want to ensure that we are only
-// attempting to open heap snapshot files and not `~/.ssh/id_rsa`, for
-// example. Therefore, the RDP only talks about snapshot ids, or transfering the
-// bulk file data. A file path can be recovered from a snapshot id, which allows
-// one to check for the presence of the heap snapshot file on the local file
-// system, but we don't have to worry about opening arbitrary files.
-//
-// The heap snapshot file path conventions permits the following forms:
-//
-//     $TEMP_DIRECTORY/XXXXXXXXXX.fxsnapshot
-//     $TEMP_DIRECTORY/XXXXXXXXXX-XXXXX.fxsnapshot
-//
-// Where the strings of "X" are zero or more digits.
