nuwa, repairment

this is a bug fix release for v0.0.8

• fix write tests for pjdfstest
• fix read/write loop test

limitations:

• disabled multithread support by default for fuse.
• write support is disabled by default, use '-o rw+' option for to enable writing. and use at your own risk.

what is next:

• binary release for mac, with prefpane automatic updater. like good old days.
• binary release for ubuntu.
• reentrant support, speed.
• robust caching.
• stable write support, needs more testings.

cheers! alper.
