This bucket allocation list (freelist) is used to create new buckets
(via \f(CW\*(C`APR::Bucket\->new\*(C'\fR)
and bucket brigades (via
\&\f(CW\*(C`APR::Brigade\->new\*(C'\fR).
.PP
You only need to use this method if you aren't running under httpd.
If you are running under mod_perl, you already have a bucket
allocation available via
\&\f(CW\*(C`$c\->bucket_alloc\*(C'\fR
and
\&\f(CW\*(C`$bb\->bucket_alloc\*(C'\fR.
.PP
Example:
.PP
.Vb 4
\&  use APR::BucketAlloc ();
\&  use APR::Pool ();
\&  my $ba = APR::BucketAlloc\->(APR::Pool\->pool);
\&  my $eos_b = APR::Bucket::eos_create($ba);

Once destroyed this object may not be used again.
.PP
You need to destroy \f(CW$ba\fR \fBonly\fR if you have created it via
\&\f(CW\*(C`APR::BucketAlloc\->new\*(C'\fR. If you try to destroy an
allocation not created by this method, you will get a segmentation
fault.
.PP
Moreover normally it is not necessary to destroy allocators, since the
pool which created them will destroy them during that pool's cleanup
phase.
