Comment(by Denis-de-Bernardy):

 re-opening with a new patch. the new regex makes it much slower, and it
 can run into backtracking problems with large strings.

 if we are to keep it, this:

 {{{
 ^(N;)|([aOs]:[0-9]+:.*[;}])|([bid]:[0-9.E+-]+;)$
 }}}

 should be:

 {{{
 ^(?:N;|[aOs]:[0-9]+:.*[;}]|[bid]:[0-9.E+-]+;)$
 }}}

 else is_serialized may return true for garbage.
