Subject: Temporary fix for coredumps during shutdown cleanup.
X-Git-Tag: take06
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=74d4c7486c53c77f1e06c3f04185b4c6f0695ca7;p=thirdparty%2Fsquid.git

Temporary fix for coredumps during shutdown cleanup.

For a permanent fix, we need to avoid deleting fd_table while it is still
in use by others, such as DeferredReads, possibly by allowing event loop
to run during shutdown.
