Code Issues

Reduce default buffer on stack size

Browse Source 
Fix segfaults on musl libc when ultrajson runs in a thread. On musl libc
the default thread stack size is only 80k so allocating a 128k buffer on
stack will guarantee a crash. There seems not to be any evident
performance benefit using big buffer on stack either so we just reduce
the default.

fixes #254
