Fixed bug #78340

Even if we know the file size, we still need to read in a loop in
case the read call returns an incomplete result.

This was less of an issue previously because we did not use the

Prevent use after free in fpm_event_epoll_wait

epoll event backend does not guarantee that child input/output events
are reported before SIGCHILD due to finished worker. While a bunch of
events received by epoll is being processed, child-related structures
may be removed before dispatching of an I/O event for the same child.
The result may be attempt to access to memory region allocated for
another purpose, segfault of the master process, and unavailable web
sites.

Postpone processing of SIGCHILD events till other events in the same
bunch are processed.
