CurlFtpFS

First of all, thanks a lot for this nice tool - good work! Really useful!

Here my problem description:
When i mount a secure ftp, produce a huge load (eg. upload a large file)
and access with another terminal the mountpoint, the software crashes with
the following message: "Software caused connection abort".
And here the output from the debug mode:
----------------------
