The signal handler for SIGINT/TERM/QUIT and, importantly, SIGPIPE tries
to write an informational message to stderr. When however stderr is
redirected to a closed pipe, this will cause (another) SIGPIPE, and in
turn the signal handler will get called again, and again and again.
Since we intend to exit rtl_fm anyways, we can just ignore this signal.
So far we had 32 * 256KB which was a bit overkill,
15 are more than enough.
15 was chosen instead of 16 because at least on Linux
there seems to be a system-wide limit of 63 transfers
(when they are 256KB large), so 4 dongles can be used
on a single machine without lowering the default transfer
number.

Use with caution, the result highly depends on the
accuracy of the clocksource your machine uses.
On some machines it may be quite accurate, on
others completely off.

This tool allows to check for lost samples (and thus check the USB
connection), as well as benchmark the Elonics E4000 tunable range.
