#2 Multi-threaded support in FUSE results in corrupted reads

[Frédéric Jouault]

Recent versions of FUSE spawn multiple threads, but the code of JoinFS (and possibly also of SplitFS) is not thread-safe.

Workaround: it is currently necessary to pass the -s option on the command line to make sure FUSE is in single-threaded mode.
This should be documented in the README.

Possible solutions:

• have main add the -s option before calling fuse_real_main when not specified by the user
• make the code thread-safe
