But such numbers can be forced with idr_get_new_above(), and that
reveals two bugs:
1) Crash in sub_remove() caused by pa array being too short.
2) Shift by more than 32 in _idr_find(), which is undefined, causing
the "outside the current tree" optimization to misfire and return NULL.
It makes no sense to talloc off the null context, then talloc steal
into the required context - just talloc off the correct context, and
change data_blob() to pass in the null context to data_blob_talloc().

when we get ECHILD in samba_runcmd it is because the parent has set
SIGCHLD to SIG_IGN. In that case the child status information is
lost. We then have to fallback on the logging of child error messages
for any useful information on what happened to the child.
A longer term fix is to stop using SIG_IGN for SIGCHLD in the standard
process model of s4.
We had a crash bug where a cached copy of a iconv convenience pointer
was used after being freed when loadparm asked for iconv to
reload. This could happen if a python module used a iconv based
function before loadparm was completed.
The fix is to ensure that any use of this pointer remains valid, by
reusing the pointer itself when it has already been initialised, but
filling in the child elements with the updated values.
In smbd there's a small gab between TALLOC_FREE(frame); before
be call smbd_parent_loop() where we don't have a valid talloc stackframe.
smbd_parent_loop() calls talloc_stackframe() only within the while(1) loop.
As DEBUG(2,("waiting for connections")) uses talloc_tos() to construct
the time header for the debug message we crash on some systems.
