array_allocate does \fInot\fR change \fIx\fR to have failed; if you want
to do that, use array_fail.
.SH PERFORMANCE
This function can call realloc when the array needs to be enlarged.
Under exceptional circumstances, this can lead to blocking the current thread.
It will also zero-fill the newly enlarged part of the array, leading to
all pages being mapped in by the operating system. If a small array is
enlarged to a very large array, this can lead to swapping and blocking.
.SH "SEE ALSO"
array_get(3), array_start(3), array_fail(3)
