+> To provide further explanation, the problem arises when a user's
+> .sh_history file grows to a size that triggers the hist_trim
+> function, but the user lacks (after the creation of .sh_history)
+> the necessary write permissions to their $HOME directory. As a

+> sh_histinit(src/cmd/ksh93/edit/history.c#L203) function and the
+> hist_trim(src/cmd/ksh93/edit/history.c#L417) function.
+>
+> Conditions for reproduction:
+>
+> 1. The size of the .sh_history file is larger than the HIST_MAX
+>    limit. (src/cmd/ksh93/edit/history.c, line 325)
+> 2. .sh_history file has not been changed in the HIST_RECENT
+>    seconds (src/cmd/ksh93/edit/history.c, line 406)
+> 3. The user does not have permission to write to the $HOME
+>    directory.

+src/cmd/ksh93/edit/history.c: hist_trim():
+- Print a warning and return if unlink(2) fails. The warning tells
+  the user to check the history file's parent directory is
+  writable. This is the best I realistically do for now, because
+  this function's basic method assumes a writable parent directory.
+- The temp file fallback is deleted because it's fundamentally
+  flawed: it assumes the temp file is made on the same volume as
+  the history file and can simply be rename(2)'d in place. Even
+  on systems where this is the case, it doesn't appear to be
+  working correctly, but this is not worth looking into.
+
