Re: Are there some potential problems if I use a self-defined memory acquirement function instead of realloc(3) in the l_alloc function?

Systems where realloc() can fail to shrink a block are not rare (as I
pointed out when this topic came up before) - in particular jemalloc,
which is the default malloc on FreeBSD, can fail this way, as can any
system which maintains a distinction between large and small blocks
(which is a fairly common design approach for malloc).
