577416d1a9 Assert allocating non-zero size memory 
Allocating zero size memory results in implementation-defined behavior:

  man:malloc(3) :
    If size is 0, then malloc() returns either NULL, or a unique pointer
    value that can later be successfully passed to free().

resuming process tracing:

81543253cf Fix misaligned access inside taskstats structure 
Reported by UB sanitizer (alongside several other messages):
linux/LinuxProcessList.c:782:25: runtime error: member access within misaligned address 0x614000000264 for type 'struct taskstats', which requires 8 byte alignment
0x614000000264: note: pointer points here
  64 01 03 00 0a 00 00 00  00 00 00 00 02 00 00 00  00 00 00 00 4b c8 2e 00  00 00 00 00 3e 45 3c fd
              ^

The issue doesn't cause trouble on x86, but any architecture with stricter memory alignment requirements may inadvertedly break.

164051354f Replace copy loop by memmove in Vector_insert 
This is basically the same change like in Vector_take,
just in the opposite direction.

1704c29b90 Use memmove for Vector_take 
Doing a quick check with callgrind this gives
an average reduction from 1804 cycles/call
down to 491 cycles/call on my test system.

The average was taken over about 40k calls.
