---------------------------------------------------------------------- 
Extra info:
-------------
If I run Asterisk using the "-p" option the system ALWAYS locks up when
calling an ODBC function or a simple "exten = h,1,Set(NAME=System(cat
/tmp/ext_name.txt))"

However if I run Asterisk without the "-p" option and use "nice" to
prioritize Asterisk (less nicer) AND  de-prioritize other processes such as
PostgreSQL making them nicer to asterisk then Asterisk slows down when
calling such processes, BUT ONLY IN THE 'H' EXTENSION.
(PS: No other large processes are active on the machine other than the
usual)

If I do not prioritize any process, so all processes are running default,
then no problem occurs... But he... that not really what we want..
