Well not everything has a reference count and not everything is static.
Some of the calls instead return a copy of the structure. If you do this
with everything that doesn't have a reference count you end up with lots
of needless Malloc() functions and you also have problems writing a
compatability wrapper because if you free the copy its gone.
I suppose you could add reference counts to everything but each one can
have a mutex operation associated with it and calling a mutex whenever
any kind of 'get' operation is needed even when you know there will
never be any kind of race condition is inefficient.
[side note the library only uses a small number of mutexes: for example
when you call X509_free(x) it uses a global lock for X509 instead of one
for the 'x' structure]
