-# Usage: do_malloc_test <test number> <options...>
-#
-# The first argument, <test number>, is an integer used to name the
-# tests executed by this proc. Options are as follows:
-#
-#     -tclprep          TCL script to run to prepare test.
-#     -sqlprep          SQL script to run to prepare test.
-#     -tclbody          TCL script to run with malloc failure simulation.
-#     -sqlbody          TCL script to run with malloc failure simulation.
-#     -cleanup          TCL script to run after the test.
-#
-# This command runs a series of tests to verify SQLite's ability
-# to handle an out-of-memory condition gracefully. It is assumed
-# that if this condition occurs a malloc() call will return a
-# NULL pointer. Linux, for example, doesn't do that by default. See
-# the "BUGS" section of malloc(3).
-#
-# Each iteration of a loop, the TCL commands in any argument passed
-# to the -tclbody switch, followed by the SQL commands in any argument
-# passed to the -sqlbody switch are executed. Each iteration the
-# Nth call to sqliteMalloc() is made to fail, where N is increased
-# each time the loop runs starting from 1. When all commands execute
-# successfully, the loop ends.
