awk: remove custom pool allocator for temporary awk variables
It seems to be designed to reduce overhead of malloc's auxiliary data, by allocating at least 64 variables as a block. With "struct var" being about 20-32 bytes long (32/64 bits), malloc overhead for one temporary indeed is high, ~33% more memory used than needed. function old new delta evaluate 3137 3145 +8 modprobe_main 798 803 +5 exec_builtin 1414 1419 +5 awk_printf 476 481 +5 as_regex 132 137 +5 EMSG_INTERNAL_ERROR 15 - -15 nvfree 169 116 -53 nvalloc 145 - -145 ------------------------------------------------------------------------------ (add/remove: 0/2 grow/shrink: 5/1 up/down: 28/-213) Total: -185 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
