[Users] Stability, and -DF_MALLOC

[Kanakatti Mahesh Subramanya]

Briefly (oh so briefly) put the version with -DF_MALLOC online, and, as 
expected, had a couple of crashes.
There was really not much information in the debug logs.
The core dumps said the following

Dump 1

Dump 2

(gdb) print ptr
$1 = (ucontact_t *) 0xc
(gdb) print act_time
$2 = 1123163783

Anything obvious leaps out at you???


Cheers, and thanx...
