Subject: Add the serialization stuff for BeOS to get us building again.
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f0952f1b51c5e007a56708fd03cf1eb7f75eddd7;p=thirdparty%2Fapache%2Fhttpd.git

Add the serialization stuff for BeOS to get us building again.

Also, stop detaching as it causes a segfault somewhere in the kernel.
I'll try to find out where and see why...
