Memory leaks in zoo_multi API
Hi,

I am using zookeeper-3.4.4 and frequently using multiupdate operations.

While running valgrind it returned following output:

==4056== 2,240 (160 direct, 2,080 indirect) bytes in 1 blocks are
definitely lost in loss record 18 of 24
==4056==    at 0x4A04A28: calloc (vg_replace_malloc.c:467)
==4056==    by 0x504D822: create_completion_entry (zookeeper.c:2322)
==4056==    by 0x5052833: zoo_amulti (zookeeper.c:3141)
==4056==    by 0x5052A8B: zoo_multi (zookeeper.c:3240)

Just curious do I need explicitly need to handle this cleanup, by
invoking some API or is this a memory leak?

It looks like completion entries for individual operations in
multiupdate transaction are not getting freed. The memory leak size
depends on the number of operations in single mutlipupdate
transaction.

Thanks & Regards,

Deepak
