incomplete replica is left, if malloc(3) fails

[gfarm-admin]

This is a sub-ticket of #408 (incomplete replica is left),
and described as comment:24:ticket:408.

this problem hardly happens, though.
(only happens at malloc(3) failure for really small size)

the main issue:
the problem happens when async_back_channel_replication_request() returns GFARM_ERR_NO_MEMORY.
it was introduced in r4480 for #37 (gfarm-2.4.0),
and exists on the 2.5 branch and 2.5.7 branch,
it doesn't exist on the main trunk, because the main truk was fixed in r6235 to implement #142 (generic send queue for backchannel for gfmd).
pointed out by Takuya Ishibashi-san (takuya-i@).

there was another issue on the trunk (and trunk only), though:
the trunk problem was introduced in r6235 to implement #142 (generic send queue for backchannel for gfmd) on the main trunk, and doesn't exist on the 2.5 branch.

Replying to takuya-i:

this problem was introduced to fix #372 in r6207 (2.5 branch, gfarm-2.5.5) and r6208 (trunk).

that was wrong. sorry for the confusion.

in reality, this problem was introduced in r6235 to implement (#142 - generic send queue for backchannel for gfmd), and doesn't exist on the 2.5 branch.

remove milestone and version from this ticket, because released versions don't have this problem.

Replying to n-soda:

this is about a problem on the main trunk.

for the main issue (i.e. the issue on the 2.5 and 2.5.7 branch) was fixed in r6909

r6909 on the 2.5 branch was merged into the 2.5.7 branch in r7363 as part of a pullup ticket #485
