Core: protect from subrequest loops.
|
||
|
|
|
||
|
|
Without protection subrequest loop results in r->count overflow and
|
||
|
|
SIGSEGV. Protection was broken in 0.7.25.
|
||
|
|
|
||
|
|
Note that this also limits number of parallel subrequests. This
|
||
|
|
wasn't exactly the case before 0.7.25 as local subrequests were
|
||
|
|
completed directly.
|
||
|
|
|
||
|
|
