[petsc-dev] writing PETSc code with no memory leaks

[Barry Smith]

   I find it very useful when writing PETSc code to keep the environmental variable 

export PETSC_OPTIONS="-malloc -malloc_debug -malloc_dump"

where I run my test programs. This helps me see memory leaks immediately (where I forgot to destroy some objects or free some memory) rather than tracking down a ton of memory leaks months later. Suggest others do the same.
