Hi there,
I think I've found a bug of thread-sleep! defined in SRFI-18 library.
The file module/srfi/srfi-18.scm line 233 subtract current time from
given timeout argument but this results negative number most of the
case. I think this line should simply return timeout as it is.
Cheers,

Hi Takashi,
Thank you for the report.

You are right. Guile's documentation indicates that the timeout is an
absolute time as a SRFI-18 time object, but the SRFI itself says that
timeouts are either:
* a time object represents an absolute point in time
* an exact or inexact real number represents a relative time in
seconds from the moment the primitive was called
So I guess when passed a number, that's not to be interpreted as an
absolute time from the epoch, but rather a relative timeout. We need to
update our documentation and tests, it seems, and issue a prominent NEWS
entry...
